CY7C64013C CY7C64113C 2.0 Functional Overview The CY7C64013C and CY7C64113C are 8-bit One Time Programmable microcontrollers that are designed for full-speed USB applications. The instruction set has been optimized specifically for USB operations, although the microcontrollers can be used for a variety of non-USB embedded applications. GPIO The CY7C64013C features 19 GPIO pins to support USB and other applications. The I/O pins are grouped into three ports (P0[7:0], P1[2:0], P2[6:2], P3[2:0])

CY7C64013C CY7C64113C 5.0 Programming Model 5.1 14-Bit Program Counter (PC) The 14-bit program counter (PC) allows access to up to 8 KB of PROM available with the CY7C64x13C architecture. The top 32 bytes of the ROM in the 8 Kb part are reserved for testing purposes. The program counter is cleared during reset, such that the first instruction executed after a reset is at address 0x0000h. Typically, this is a jump instruction to a reset handler that initializes the application (see Interrupt V

CY7C64013C CY7C64113C 5.2 8-Bit Accumulator (A) The accumulator is the general-purpose register for the microcontroller. 5.3 8-Bit Temporary Register (X) The “X” register is available to the firmware for temporary storage of intermediate results. The microcontroller can perform indexed operations based on the value in X. Refer to Section 5.6.3 for additional information. 5.4 8-Bit Program Stack Pointer (PSP) During a reset, the program stack pointer (PSP) is set to 0x00 and “grows” upward fr

CY7C64013C CY7C64113C 5.5 8-Bit Data Stack Pointer (DSP) The data stack pointer (DSP) supports PUSH and POP instructions that use the data stack for temporary storage. A PUSH instruction pre-decrements the DSP, then writes data to the memory location addressed by the DSP. A POP instruction reads data from the memory location addressed by the DSP, then post-increments the DSP. During a reset, the DSP is reset to 0x00. A PUSH instruction when DSP equals 0x00 writes data at the top of the data

Clock Oscillator On-Chip Circuit The XTALIN and XTALOUT are the clock pins to the microcontroller. The user can connect an external oscillator or a crystal to these pins. When using an external crystal, keep PCB traces between the chip leads and crystal as short as possible (less than 2 cm). A 6-MHz fundamental frequency parallel resonant crystal can be connected to these pins to provide

Watchdog Reset (WDR) The USB transmitter is disabled by a Watchdog Reset because the USB Device Address Register is cleared (see Section 18.1). Otherwise, the USB Controller would respond to all address 0 transactions. It is possible for the WDR bit of the Processor Status and Control Register (0xFF) to be set following a POR e
