The award winning PSoC Designer software and PSoC silicon are an integrated unit. The quickest path to understanding the PSoC silicon is through the PSoC Designer software GUI. This data sheet is useful for understanding the details of the PSOC integrated circuit, but is not a good starting point for a new PSoC developer seeking to get a general overview of this new technology. PSoC developers are NOT required to build their own ADCs, DACs, and other peripherals. Embedded in the PSoC Designer software are the individual data sheets, performance graphs, and PSoC User Modules (graphically selected code packets) for the peripherals, such as the incremental ADCs, DACs, LCD controllers, op amps, low-pass filters, etc. With simple GUI-based selection, placement, and connection, the basic architecture of a design may be developed within PSoC Designer software without ever writing a single line of code. Development Kits are available from the following distributors: Digi-Key, Avnet, Arrow, and Future. The Cypress Online Store also contains development kits, C compilers, and all accessories for PSoC development. Go to the Cypress Online Store web site at http://www.cypress.com, click the Online Store shopping cart icon at the bottom of the web page, and click PSoC (Programmable System-on-Chip) to view a current list of available items.

Any pin can serve as an interrupt source, and can be selected to trigger on positive edges, negative edges, or any change. Digital signal sources can be routed directly from a pin to the digital PSoC blocks. Some pins have additional capability to route analog signals to the analog PSoC blocks. Multiple oscillator options are available for use in clocking the CPU, analog PSoC blocks and digital PSoC blocks. These options include an internal main oscillator running at 48/24 MHz, an external crystal oscillator for use with a 32.768 kHz watch crystal, and an internal lowspeed oscillator for use in clocking the PSoC blocks and the Watchdog/Sleep timer. User selectable clock divisors allow for optimizing code execution speed and power trade-offs. The different device types in this family provide various amounts of code and data memory. The code space ranges in size from 4K to 16K bytes of user programmable Flash memory. This memory can be programmed serially in either a programming Pod or on the user board. The endurance on the Flash memory is 50,000 erase/write cycles. The data space is 256 bytes of user SRAM. A powerful and flexible protection model secures the user’s sensitive information. This model allows the user to selectively lock blocks of memory for read and write protection. This allows partial code updates without exposing proprietary information. Devices in this family range from 8 pins through 48 pins in PDIP, SOIC and SSOP packages. The CPU heart of this next generation family of microcontrollers is a high performance, 8-bit, M8C Harvard architecture microprocessor. Separate program and memory busses allow for faster overall throughput. Processor clock speeds to 24 MHz are available. The processor may also be run at lower clock speeds for powersensitive applications. A rich instruction set allows for efficient low-level language support. All devices in this family include both analog and digital configurable peripherals (PSoC blocks). These blocks enable the user to define unique functions during configuration of the device. Included are twelve analog PSoC blocks and eight digital PSoC blocks. Potential applications for the digital PSoC blocks are timers, counters, UARTs, CRC generators, PWMs, and other functions. The analog PSoC blocks can be used for SAR ADCs, Multi-slope ADCs, programmable gain amplifiers, programmable filters, DACs, and other functions. Higher order User Modules such as modems, complex motor controllers, and complete sensor signal chains can be created from these building blocks. This allows for an unprecedented level of flexibility and integration in microcontroller-based systems. A Multiplier/Accumulator (MAC) is available on all devices in this family. The MAC is implemented on this device as a peripheral that is mapped into the register space. When an instruction writes to the MAC input registers, the result of an 8x8 multiply and a 32-bit accumulate are available to be read from the output registers on the next instruction cycle. The number of general purpose I/Os available in this family of parts range from 6 to 44. Each of these I/O pins has a variety of programmable options.

Architecture Introduction RET instructions, which manage the software stack. It can also be affected by the SWAP and ADD instructions. The Flag Register (CPU_F) has three status bits: Zero Flag bit [1]; Carry Flag bit [2]; Supervisory State bit [3]. The Global Interrupt Enable bit [0] is used to globally enable or disable interrupts. An extended I/O space address, bit [4], is used to determine which bank of the register space is in use. The user cannot manipulate the Supervisory State status bit [3]. The flags are affected by arithmetic, logic, and shift operations. The manner in which each flag is changed is dependent upon the instruction being executed (i.e., AND, OR, XOR... See Table 23 on page 25). This family of microcontrollers is based on a high performance, 8-bit, Harvard architecture microprocessor. Five registers control the primary operation of the CPU core. These registers are affected by various instructions, but are not directly accessible through the register space by the user. For more details on addressing with the register space, see section 4.0. Table 7: CPU Registers and Mnemonics Register Mnemonic Flags Program Counter Accumulator Stack Pointer Index CPU_F CPU_PC CPU_A CPU_SP CPU_X The 16 bit Program Counter Register (CPU_PC) allows for direct addressing of the full 16 Kbytes of program memory space available in the largest members of this family. This forms one contiguous program space, and no paging is required. The Accumulator Register (CPU_A) is the general-purpose register that holds the results of instructions that specify any of the source addressing modes. The Index Register (CPU_X) holds an offset value that is used in the indexed addressing modes. Typically, this is used to address a block of data within the data memory space. The Stack Pointer Register (CPU_SP) holds the address of the current top-of-stack in the data memory space. It is affected by the PUSH, POP, LCALL, CALL, RETI, and May 17, 2005 Document #: 38-12010 CY Rev. *C 19 CY8C25122/CY8C26233/CY8C26443/CY8C26643 Device Family Data Sheet 2.2 2.2.1 CPU Registers Flags Register The Flags Register can only be set or reset with logical instruction.

The result of an instruction using this addressing mode is placed within the RAM memory. Operand 1 is the address of the result. Operand 2 is an address that points to a location in the RAM memory that is the source for the instruction. This addressing mode is only valid on the MOV instruction. The instruction using this addressing mode is three bytes in length. 2.3.10 Destination Indirect Post Increment The result of an instruction using this addressing mode is placed within the memory space. Operand 1 is an address pointing to a location within the memory space, which contains an address (the indirect address) for the destination of the instruction. The indirect address is incremented as part of the instruction execution. The source for the instruction is the Accumulator. This addressing mode is only valid on the MVI instruction. The instruction using this addressing mode is two bytes in length.
