Offered in 40-pin DIP, 44-pin PLCC or 44-pin LQFP package styles, these devices are pin-compatible EPROM versions of the Z86C61/ 63. The ROMless pin option is available on the 44-pin versions only. With 16 KB/32 KB of ROM and 236 bytes of general-purpose RAM, the Z86E61/Z86E63 MCU offers fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion. For applications demanding powerful I/O capabilities, the Z86E61/Z86E63 MCU offers 32 pins dedicated to input and output. These lines are grouped into four ports. Each port consists of eight lines, and is configurable under software control to provide timing, status signals, serial or parallel I/O with or without handshake, and an address/data bus for interfacing external memory. The Z86E61/Z86E63 MCU can address both external memory and preprogrammed ROM, making it well suited for high-volume applications or where code flexibility is required. There are three basic address spaces available to support this configuration: • • • Program memory Data memory 236 General-purpose registers Features The Z86E61 and Z86E63 MCUs offer the following features: • • • • • • • • • PS014404-0212 8-Bit CMOS microcontroller 40-pin DIP, 44-pin PLCC and 44-pin LQFP packages 4.5 V to 5.5 V operating range Clock speeds: 16 MHz and 20 MHz Low power consumption: 275 mW (max) Two Standby modes: STOP and HALT 32 Input/Output lines Full-duplex UART All digital inputs are TTL levels Overview Z86E61/Z86E63 Microcontrollers Product Specification 2 • • • • Auto Latches • 256-byte Register File: – 236 bytes of General-Purpose RAM – 16 bytes of Control and Status registers – 4 bytes for ports • • • Two programmable 8-bit Counter/Timers, each with 6-bit programmable prescaler High-voltage protection on high-voltage inputs RAM and EPROM Protect EPROM: – 16 KB Z86E61 – 32 KB Z86E63 Six vectored priority interrupts from eight different sources On-chip oscillator that accepts a crystal ceramic resonator, LC or external clock drive To unburden the system from coping with real-time tasks such as counting/timing and serial data communication, the Z86E61/Z86E63 MCU offers two on-chip counter/timers with a large number of user selectable modes.

ROMless (Input, Active Low) Connecting this pin to GND disables the internal ROM and forces the device to function as a Z86C91 ROMless Z8 (see the Z86C91 product specification for more information). When pulled High to VCC, the device functions as a normal Z86E61/Z86E63 EPROM version. This pin is only available on the 44-pin versions of the Z86E61/Z86E63 MCU. DS (Output, Active Low) Data Strobe is activated once for each external memory transfer. For a READ operation, data must be available prior to the trailing edge of DS. For WRITE operations, the falling edge of DS indicates that output data is valid. AS (Output, Active Low) Address Strobe is pulsed once at the beginning of each machine cycle. Address output is through Port 1 for all external programs. Memory address transfers are valid at the trailing edge of AS. Under program control, AS can be placed in the high-impedance state along with Ports 0 and 1, Data Strobe, and Read/Write. XTAL2, XTAL1 Crystal 2, Crystal 1 (time-based input and output, respectively). These pins connect a parallel-resonant crystal, ceramic resonator, LC, or any external single-phase clock to the onchip oscillator and buffer. R/W (Output, Write Low) The Read/Write signal is Low when the MCU is writing to the external program or data memory. RESET (Input, Active Low) To avoid asynchronous and noisy reset problems, the Z86E61/Z86E63 MCU is equipped with a reset filter of four external clocks (4TpC). If the external RESET signal is less than 4TpC in duration, no reset occurs. On the fifth clock after the RESET is detected, an internal RST signal is latched and held for an internal register count of 18 external clocks, or for the duration of the external RESET, whichever is longer. During the reset cycle, DS is held active Low while AS cycles at a rate of TpC/2. When RESET is deactivated, program execution begins at location 000Ch. Power-up reset time must be held low for 50 ms, or until VCC is stable, whichever is longer. PS014404-0212 Pin Functions Z86E61/Z86E63 Microcontrollers Product Specification 12 Port 0 (P07–P00) Port 0 is an 8-bit, nibble programmable, bidirectional, TTL compatible port. These eight I/ O lines can be configured under software control as a nibble I/O port, or as an address port for interfacing external memory. When used as an I/O port, Port 0 may be placed under handshake control. In this configuration, Port 3, lines P32 and P35 are used as the handshake control DAV0 and RDY0 (Data Available and Ready). Handshake signal assignment is dictated by the I/O direction of the upper nibble P07–P04. The lower nibble must have the same direction as the upper nibble to be under handshake control. For external memory references, Port 0 can provide address bits A11–A8 (lower nibble) or A15–A8 (lower and upper nibbles) depending on the required address space. If the address range requires 12 bits or less, the upper nibble of Port 0 can be programmed independently as I/O while the lower nibble is used for addressing. If one or both nibbles are needed for I/O operation, they must be configured by writing to the Port 0 Mode Register. In ROMless Mode, after a hardware reset, the Port 0 lines are defined as address lines A15–A8, and extended timing is set to accommodate slow memory access. The initialization routine can include reconfiguration to eliminate this extended timing mode; see Figure 8.

Port 0 Configuration Port 1 (P17–P10) Port 1 is an 8-bit, byte programmable, bidirectional, TTL compatible port. It has multiplexed Address (A7–A0) and Data (D7–D0) ports. For the Z86E61/Z86E63 MCU, these eight I/O lines can be programmed as input or output lines or are configured under software control as an address/data port for interfacing external memory. When used as an I/O port, Port 1 can be placed under handshake control. In this configuration, Port 3 lines, P33 and P34, are used as the handshake controls RDY1 and DAV1. Memory locations greater than 16384 (Z86E61) or 32768 (Z86E63) are referenced through Port 1. To interface external memory, Port 1 must be programmed for the multi- PS014404-0212 Pin Functions Z86E61/Z86E63 Microcontrollers Product Specification 14 plexed Address/ Data Mode. If more than 256 external locations are required, Port 0 must output the additional address lines. Port 1 can be placed in high-impedance state along with Port 0, AS, DS, and R/W, allowing the MCU to share common resources in multiprocessor and DMA applications. Data transfers are controlled by assigning P33 as a Bus Acknowledge input, and P34 as a Bus Request output; see Figure 9. 8 Port 1 (AD7-AD0) Z86E61 Z86E63 MCU Handshake controls DAV1 and RDY1 (P33 and P34) OEN PAD Out TTL Level Shifter In Auto Latch R = 500 kΩ Figure 9. Port 1 Configuration Port 2 (P27–P20) Port 2 is an 8-bit, bit programmable, bi-directional, CM0S compatible port. Each of these eight I/0 lines can be independently programmed as an input or output, or globally as an PS014404-0212 Pin Functions Z86E61/Z86E63 Microcontrollers Product Specification 15 open-drain output. Port 2 is always available for I/ 0 operation. When used as an I/0 port, Port 2 can be placed under handshake control. In this configuration, Port 3 lines P31 and P36 are used as the handshake control lines DAV2 and RDY2. The handshake signal assignment for Port 3 lines, P31 and P36, is dictated by the direction (input or output) assigned to P27; see Figure 10 and Table 31 on page 16).

These eight I/O lines have four-fixed (P33–P30) input and four-fixed (P37–P34) output ports. Port 3, when used as serial I/O, is programmed as serial in and serial out, respectively; see Figure 11. Z86E61 Z86E63 MCU Port 3 (I/O or Control) Figure 11. Port 3 Configuration Port 3 is configured under software control to provide the following control functions: handshake for Ports 0 and 2 (DAV and RDY); four external interrupt request signals (IRQ3–IRQ0); timer input and output signals (TIN and TOUT) Data Memory Select (DM) and EPROM control signals (P30 = CE, P31 = OE, P32 = EPM and P33 = VPP).

Port 3 lines, P37 and P30, are programmed as serial I/0 lines for fullduplex serial asynchronous receiver/transmitter operation. The bit rate is controlled by Counter/ Timer0. The Z86E61/Z86E63 MCU automatically adds a start bit and two stop bits to transmitted data; see Figure 12. Odd parity is also available as an option. Eight data bits are always transmitted, regardless of parity selection. If parity is enabled, the eighth bit is the odd parity bit. An interrupt request (IRQ4) is generated on all transmitted characters. Received data must have a start bit, eight data bits, and at least one stop bit. If parity is on, bit 7 of the received data is replaced by a parity error flag. Received characters generate the IRQ3 interrupt request.

Serial Data Formats Auto Latch. The Auto Latch puts valid CMOS levels on all CMOS inputs that are not externally driven. This reduces excessive supply current flow in the input buffer when it is not driven by any source. Note: P33–P30 inputs differ from the Z86C61/C63 in that there is no clamping diode to VCC because of the EPROM high voltage detection circuits. Exceeding the VIH maximum specification during standard operating mode may cause the device to enter EPROM Mode. PS014404-0212 Pin Functions Z86E61/Z86E63 Microcontrollers Product Specification 18 Address Space This section describes the memory and addressing functions of the Z86E61/Z86E63 MCU. Program Memory The Z86E61/Z86E63 MCU can address 48 KB (Z86E61) or 32 KB (Z86E63) of external program memory; see Figure 13. The first 12 bytes of program memory are reserved for the interrupt vectors. These locations contain six 16-bit vectors that correspond to the six available interrupts. For EPROM Mode, byte 13 to byte 16383 (Z86E61) or 32767 (Z86E63) consists of on-chip EPROM. At addresses 16384 (Z86E61) or 32768 (Z86E63) and above, the Z86E61/Z86E63 MCU executes external program memory fetches. In ROMless Mode, the Z86E61/Z86E63 MCU can address up to 64 KB of program memory. Program execution begins at external location 000C (HEX) after a reset. 65535 16384 (E61) 32768 (E63) 16383 (E61) 32767 (E63) Location of First Byte of Instruction Executed After RESET Interrupt Vector (Lower Byte) Interrupt Vector (Upper Byte) External ROM and RAM On-Chip PROM 12 11 IRQ5 10 IRQ5 9 IRQ4 8 IRQ4 7 IRQ3 6 IRQ3 5 IRQ2 4 IRQ2 3 IRQ1 2 IRQ1 1 IRQ0 0 IRQ0 Figure 13. Program Memory Configuration PS014404-0212 Pin Functions Z86E61/Z86E63 Microcontrollers Product Specification 19 Data Memory The EPROM version can address up to 48 KB (Z86E61) or 32 KB (Z86E63) of external data memory (DM) space beginning at location 16384 (Z86E61) or 32768 (Z86E63). The ROMless version can address up to 64 KB of external data memory. External data memory may be included with, or separated from, the external program memory space. DM, an optional I/0 function that can be programmed to appear on pin P34, is used to distinguish between data and program memory space; see Figure 14. The state of the DM signal is controlled by the type instruction being executed. An LDC opcode references PROGRAM (DM inactive) memory, and an LDE instruction references DATA (DM active Low) memory. 65535 External Data Memory 32768 (E63) 16384 (E61) 16383 (E61) 32767 (E63) Not Addressable 0 Figure 14.

The instructions can access registers directly or indirectly through an 8-bit address field. The Z86E61/Z86E63 MCU also allows short 4-bit register addressing using the Register Pointer, which is shown in Figure 16. In 4-bit mode, the Register File is divided into 16 working register groups, each occupying 16 continuous locations. The Register Pointer addresses the starting location of the active working register group.

Register Pointer Stack The Z86E61/Z86E63 MCU has a 16-bit Stack Pointer (R255–R254) used for external stacks that reside anywhere in the data memory for the ROMless Mode, but only from 16384 (Z86E61) or 32768 (Z86E63) to 65535 in the EPROM Mode. An 8-bit Stack Pointer (R255) is used for the internal stack that resides within the 236 general-purpose registers (R239–R4). The high byte of the Stack Pointer (SPH Bits 15–8) can be use as a general-purpose register when using internal stack only. PS014404-0212 Pin Functions Z86E61/Z86E63 Microcontrollers Product Specification 22 Functional Description This section describes the counter/timer, interrupt, clock and timer mode functions of the Z86E61/Z86E63 MCU. Counter/Timers There are two 8-bit programmable counter/timers (T0–T1), each driven by its own 6-bit programmable prescaler. The T1 prescaler is driven by internal or external clock sources; however, the T0 prescaler is driven by the internal clock only, as shown in Figure 17. Internal Data Bus Write Write OSC Read PRE0 Initial Value Register T0 Initial Value Register 6-Bit Down Counter 8-Bit Down Counter T0 Current Value Register +2 +4 Internal Clock IRQ4 Serial I/O Clock +2 External Clock T OUT P36 Clock Logic +4 Internal Clock Gated Clock Triggered Clock T IN P31 Write 6-Bit Down Counter 8-Bit Down Counter PRE1 Initial Value Register T1 Initial Value Register Write IRQ5 T1 Current Value Register Read Internal Data Bus Figure 17. Counter/Timers Block Diagram PS014404-0212 Pin Functions Z86E61/Z86E63 Microcontrollers Product Specification 23 The 6-bit prescalers can divide the input frequency of the clock source by any integer number from 1 to 64. Each prescaler drives its counter, which decrements the value (1 to 256) that has been loaded into the counter. When both the counters and prescalers reach the end of the count, a timer interrupt request, IRQ4 (T0) or IRQ5 (T1), is generated. The counter is programmed to start, stop, restart to continue, or restart from the initial value. The counters can also be programmed to stop upon reaching zero (Single Pass Mode) or to automatically reload the initial value and continue counting (Modulo-n Continuous Mode). The counter, but not the prescalers, are read at any time without disturbing their value or count mode. The clock source for T1 is user-definable and is either the internal microprocessor clock divided-by-four, or an external signal input through Port 3. The Timer Mode Register configures the external timer input (P31) as an external clock, a trigger input that can be retriggerable or non-retriggerable, or as a gate input for the internal clock. Port 3 line P36 also serves as a timer output (TOUT) through which T0, T1, or the internal clock can be output. The counter/timers are cascaded by connecting the T0 output to the input of T1. Interrupts The Z86E61/Z86E63 MCU has six different interrupts from eight different sources. The interrupts are maskable and prioritized. The eight sources are divided as follows: four sources are claimed by Port 3 lines P33–P30, one in Serial Out, one in Serial In, and two in the counter/timers; see Figure 18. The Interrupt Mask Register globally or individually enables or disables the six interrupt requests. When more than one interrupt is pending, priorities are resolved by a programmable priority encoder that is controlled by the Interrupt Priority Register; see Figure 40 on page 48. All Z86E61/Z86E63 MCU interrupts are vectored through locations in the program memory. When an interrupt machine cycle is activated, an interrupt request is granted. Thus, this disables all of the subsequent interrupts, saves the Program Counter and Status Flags, and then branches to the program memory vector location reserved for that interrupt. This memory location and the next byte contain the 16-bit address of the interrupt service routine for that particular interrupt request. To accommodate polled interrupt systems, interrupt inputs are masked and the Interrupt Request Register is polled to determine which of the interrupt requests need service. Software initialized interrupts are supported by setting the appropriate bit in the Interrupt Request Register (IRQ). Internal interrupt requests are sampled on the falling edge of the last cycle of every instruction, and the interrupt request must be valid 5TpC before the falling edge of the last clock cycle of the currently executing instruction.

Interrupt Block Diagram For the ROMless Mode, when the device samples a valid interrupt request, the next 48 (external) clock cycles are used to prioritize the interrupt, and push the two PC bytes and the Flag Register on the stack. The following nine cycles are used to fetch the interrupt vector from external memory. The first byte of the interrupt service routine is fetched beginning on the 58th TpC cycle following the internal sample point, which corresponds to the 63rd TpC cycle following the external interrupt sample point. Clock The Z86E61/Z86E63 MCU’s on-chip oscillator features a high gain, parallel resonant amplifier for connection to a crystal, LC, ceramic resonator, or any suitable external clock source (XTAL1 = Input, XTAL2 = Output). The crystal should be AT cut, 1 MHz to 20 MHz max; series resistance (RS) is less than or equal to 100 Ohms. The crystal should be connected across XTAL1 and XTAL2 using the recommended capacitors (10 pF < CL < 100 pF) from each pin to ground; see Figure 19.

Oscillator Configuration Note: The actual capacitor value is specified by the crystal manufacturer. HALT Turns off the internal CPU clock but not the XTAL oscillation. The counter/timers and external interrupts IRQ0, IRQ1, IRQ2, and IRQ3 remain active. The devices are recovered by interrupts, either externally or internally generated. An interrupt request must be executed (enabled) to exit HALT Mode. After the interrupt service routine, the program continues from the instruction after the HALT. STOP This instruction turns off the internal clock and external crystal oscillation, and reduces the standby current to 5 µA (typical) or less. The STOP Mode is terminated by a reset, which causes the processor to restart the application program at address 000Ch. To enter STOP (or HALT) Mode, it is necessary to first flush the instruction pipeline to avoid suspending execution in mid-instruction. To do this, the user must execute a NOP (opcode = 0FFH) immediately before the appropriate SLEEP instruction, as shown in the following code segment.

This is accomplished by driving the EPM pin (P32) to VH and activating CE and OE. PGM remains inactive. This mode is not valid after execution of an EPROM protect cycle. Timing for the EPROM read cycle is shown in Figure 20.

EPROM Read Timing User MODE 2: EPROM Program The Z86E61/Z86E63 MCU’s Program function conforms to the Intelligent programming algorithm. The device is programmed with VCC, at 6.0 V and VPP = 12.5 V. Programming pulses are applied in 1 ms increments to a maximum of 25 pulses before proper verification. After verification, a programming pulse of three times the duration of the cycles necessary to program the device is issued to ensure proper programming. After all addresses are programmed, a final data comparison is executed and the programming cycle is complete. Timing for the Z86E61/Z86E63 MCU programming cycle is shown in Figure 21.

EPROM Program and Verify Timing User Mode 3: PROM Verify The Program Verify cycle is used as part of the intelligent programming algorithm to insure data integrity under worst-case conditions. It differs from the EPROM Read cycle in that VPP is active and VCC must be driven to 6.0 V. Timing is shown in Figure 21. User Modes 4 and 5: EPROM and RAM Protect To extend program security, EPROM and RAM protect cycles are provided for the Z86E61/Z86E63 MCU. Execution of the EPROM protect cycle prohibits proper execution of the EPROM Read, EPROM Verify, and EPROM programming cycles. Execution of the RAM protect cycle disables accesses to the upper 128 bytes of register memory (excluding PS014404-0212 Pin Functions Z86E61/Z86E63 Microcontrollers Product Specification 30 mode and configuration registers), but first the user’s program must set bit 6 of the IMR (R251).

Programming EPROM and RAM Protect Z86E63 Signal Description for EPROM Program/Read The following signals are required to correctly program or read the Z86E63 device. ADDR The address must remain stable throughout the program read cycle. On both the Z86E61 and Z86E63 MCUs, all A0–A14 address lines must be driven at all times. PS014404-0212 Pin Functions Z86E61/Z86E63 Microcontrollers Product Specification 31 DATA The I/O data bus must be stable during programming (OE High, PGM Low, VPP High). During read the data bus outputs data. XCLK A clock is required to clock the RESET signal into the registers before programming. A constant clock can be applied, or the XCLK input can be toggled a minimum of 12 cycles before any programming or verify function begins. The maximum clock frequency to be applied when in the EPROM Mode is 12 MHz. RESET. The reset input can be held to a constant Low or High value throughout normal programming. It must be held High to program the EPROM protect option bit. Also, any time the RESET input changes state the XCLK must be clocked a minimum of 12 times to clock the RESET through the reset filter. OE. When the device is placed in EPROM Mode, the OE input also serves as the precharge for the sense amp. The precharge signal should be Low for the first half of the stable address and High for the second half. The PRECHG signal is inverted from the OE signal so the OE should be High on the first half and Low on the second half, or stable address. The EPROM output data should be sampled during the second half of stable address. The access time of the EPROM is defined in later sections. This two part calculation of access time is required because this is a precharged sense amp with a precharge clock. Programming Flow Figure 23 shows the steps for programming the Z86E61/Z86E63 MCU.
