DATASHEET 82C84A FN2974 Rev 4.00 Sep 9, 2015 CMOS Clock Generator Driver The Intersil 82C84A is a high performance CMOS Clock Generator-driver which is designed to service the requirements of both CMOS and NMOS microprocessors such as the 80C86, 80C88, 8086 and the 8088. The chip contains a crystal controlled oscillator, a divide-by-three counter and complete “Ready” synchronization and reset logic. Static CMOS circuit design permits operation with an external frequency source from DC to 25MHz. Crystal controlled operation to 25MHz is guaranteed with the use of a parallel, fundamental mode crystal and two small load capacitors. All inputs (except X1 and RES) are TTL compatible over temperature and voltage ranges. Power consumption is a fraction of that of the equivalent bipolar circuits. This speed-power characteristic of CMOS permits the designer to custom tailor his system design with respect to power and/or speed requirements. Features • Generates the System Clock For CMOS or NMOS Microprocessors • Up to 25MHz Operation • Uses a Parallel Mode Crystal Circuit or External Frequency Source • Provides Ready Synchronization • Generates System Reset Output From Schmitt Trigger Input • TTL Compatible Inputs/Outputs • Very Low Power Consumption • Single 5V Power Supply • Operating Temperature Ranges - C82C84A . . . . . . . . . . . . . . . . . . . . . . . . . 0°C to +70°C - I82C84A . . . . . . . . . . . . . . . . . . . . . . . . . -40°C to +85°C - M82C84A . . . . . . . . . . . . . . . . . . . . . . . -55°C to +125°C • Pb-Free Plus Anneal Available (RoHS Compliant) Pinouts 3 16 X2 RDY1 4 15 ASYNC READY 5 14 EFI RDY2 6 13 F/C AEN2 7 12 OSC CLK 8 11 RES GND 9 10 RESET FN2974 Rev 4.00 Sep 9, 2015 RDY1 4 READY 5 RDY2 6 AEN2 7 NC 8 NO X1 AEN1 3 2 1 20 19 LO NG ER AI AV LA E BL O R ED RT O PP18 X2 U S 9 10 11 12 13 OSC X1 VCC 17 RES 2 CSYNC PCLK RESET VCC PCLK 18 GND 1 CLK CSYNC AEN1 82C84A (PLCC, CLCC) TOP VIEW 82C84A (PDIP, CERDIP) TOP VIEW 17 ASYNC 16 EFI 15 F/C 14 NC Page 1 of 13 82C84A Ordering Information PART NUMBER PART MARKING TEMP.

AEN serves to qualify its respective Bus Ready Signal (RDY1 or RDY2). AEN1 validates RDY1 while AEN2 validates RDY2. Two AEN signal inputs are useful in system configurations which permit the processor to access two Multi-Master System Busses. In non-Multi-Master configurations, the AEN signal inputs are tied true (LOW). RDY1, RDY2 4, 6 I BUS READY (Transfer Complete). RDY is an active HIGH signal which is an indication from a device located on the system data bus that data has been received, or is available RDY1 is qualified by AEN1 while RDY2 is qualified by AEN2. ASYNC 15 I READY SYNCHRONIZATION SELECT: ASYNC is an input which defines the synchronization mode of the READY logic. When ASYNC is low, two stages of READY synchronization are provided. When ASYNC is left open or HIGH, a single stage of READY synchronization is provided. READY 5 O READY: READY is an active HIGH signal which is the synchronized RDY signal input. READY is cleared after the guaranteed hold time to the processor has been met. X1, X2 17, 16 IO CRYSTAL IN: X1 and X2 are the pins to which a crystal is attached. The crystal frequency is 3 times the desired processor clock frequency, (Note 1). F/C 13 I FREQUENCY/CRYSTAL SELECT: F/C is a strapping option. When strapped LOW. F/C permits the processor’s clock to be generated by the crystal. When F/C is strapped HIGH, CLK is generated for the EFI input, (Note 1). EFI 14 I EXTERNAL FREQUENCY IN: When F/C is strapped HIGH, CLK is generated from the input frequency appearing on this pin. The input signal is a square wave 3 times the frequency of the desired CLK output. CLK 8 O PROCESSOR CLOCK: CLK is the clock output used by the processor and all devices which directly connect to the processor’s local bus. CLK has an output frequency which is 1/3 of the crystal or EFI input frequency and a 1/3 duty cycle. PCLK 2 O PERIPHERAL CLOCK: PCLK is a peripheral clock signal whose output frequency is 1/2 that of CLK and has a 50% duty cycle. OSC 12 O OSCILLATOR OUTPUT: OSC is the output of the internal oscillator circuitry. Its frequency is equal to that of the crystal. RES 11 I RESET IN: RES is an active LOW signal which is used to generate RESET. The 82C84A provides a Schmitt trigger input so that an RC connection can be used to establish the power-up reset of proper duration. RESET 10 O RESET: RESET is an active HIGH signal which is used to reset the 80C86 family processors. Its timing characteristics are determined by RES. CSYNC 1 I CLOCK SYNCHRONIZATION: CSYNC is an active HIGH signal which allows multiple 82C84As to be synchronized to provide clocks that are in phase. When CSYNC is HIGH the internal counters are reset. When CSYNC goes LOW the internal counters are allowed to resume counting. CSYNC needs to be externally synchronized to EFI. When using the internal oscillator CSYNC should be hardwired to ground. GND 9 Ground VCC 18 VCC: The +5V power supply pin. A 0.1F capacitor between VCC and GND is recommended for decoupling. NOTE: 1. If the crystal inputs are not used X1 must be tied to VCC or GND and X2 should be left open. FN2974 Rev 4.00 Sep 9, 2015 Page 4 of 13 82C84A Functional Description Oscillator The oscillator circuit of the 82C84A is designed primarily for use with an external parallel resonant, fundamental mode crystal from which the basic operating frequency is derived. The crystal frequency should be selected at three times the required CPU clock. X1 and X2 are the two crystal input crystal connections. For the most stable operation of the oscillator (OSC) output circuit, two capacitors (C1 = C2) as shown in the waveform figures are recommended. The output of the oscillator is buffered and brought out on OSC so that other system timing signals can be derived from this stable, crystal-controlled source. TABLE 1. CRYSTAL SPECIFICATIONS PARAMETER TYPICAL CRYSTAL SPEC Frequency 2.4 - 25MHz, Fundamental, “AT” cut Type of Operation Parallel Unwanted Modes 6dB (Minimum) Load Capacitance 18 - 32pF Capacitors C1, C2 are chosen such that their combined capacitance C1 x C2 CT = ---------------------- (Including stray capacitance) C1 + C2 matches the load capacitance as specified by the crystal manufacturer. This ensures operation within the frequency tolerance specified by the crystal manufacturer. Clock Generator The clock generator consists of a synchronous divide-bythree counter with a special clear input that inhibits the counting. This clear input (CSYNC) allows the output clock to be synchronized with an external event (such as another 82C84A clock). It is necessary to synchronize the CSYNC input to the EFI clock external to the 82C84A. This is accomplished with two flip-flops. (See Figure 1). The counter output is a 33% duty cycle clock at one-third the input frequency. NOTE: The F/C input is a strapping pin that selects either the crystal oscillator or the EFI input as the clock for the  3 counter. If the EFI input is selected as the clock source, the oscillator section can be used independently for another clock source. Output is taken from OSC. Clock Outputs The CLK output is a 33% duty cycle clock driver designed to drive the 80C86, 80C88 processors directly. PCLK is a peripheral clock signal whose output frequency is 1/2 that of CLK. PCLK has a 50% duty cycle. Reset Logic The reset logic provides a Schmitt trigger input (RES) and a synchronizing flip-flop to generate the reset timing. The reset signal is synchronized to the falling edge of CLK. A simple RC network can be used to provide power-on reset by utilizing this function of the 82C84A. READY Synchronization Two READY input (RDY1, RDY2) are provided to accommodate two system busses. Each input has a qualifier (AEN1 and AEN2, respectively). The AEN signals validate their respective RDY signals. If a Multi-Master system is not being used the AEN pin should be tied LOW. Synchronization is required for all asynchronous active-going edges of either RDY input to guarantee that the RDY setup and hold times are met. Inactive-going edges of RDY in normally ready systems do not require synchronization but must satisfy RDY setup and hold as a matter of proper system design. The ASYNC input defines two modes of READY synchronization operation. When ASYNC is LOW, two stages of synchronization are provided for active READY input signals. Positive-going asynchronous READY inputs will first be synchronized to flipflop one of the rising edge of CLK (requiring a setup time tR1VCH) and the synchronized to flip-flop two at the next falling edge of CLK, after which time the READY output will go active (HIGH). Negative-going asynchronous READY inputs will be synchronized directly to flip-flop two at the falling edge of CLK, after which the READY output will go inactive. This mode of operation is intended for use by asynchronous (normally not ready) devices in the system which cannot be guaranteed by design to meet the required RDY setup timing, TR1VCL, on each bus cycle. When ASYNC is high or left open, the first READY flip-flop is bypassed in the READY synchronization logic. READY inputs are synchronized by flip-flop two on the falling edge of CLK before they are presented to the processor. This mode is available for synchronous devices that can be guaranteed to meet the required RDY setup time. ASYNC can be changed on every bus cycle to select the appropriate mode of synchronization for each device in the system.
