CY7C63001A-PC

Application Specific Microcontrollers Overview

The CY7C63001A-PC is a low-cost, 8-bit RISC One Time Programmable (OTP) microcontroller featuring a built-in 1.5-Mbps USB Serial Interface Engine (SIE). It operates on a 6-MHz external ceramic resonator, which is doubled internally to provide a 12-MHz clock for the processor core. The device includes 4 Kbytes of EPROM and 128 bytes of internal RAM. Designed for low-speed USB peripherals, it supports one device address and two endpoints (one control, one data). Key features include up to 16 Schmitt trigger I/O pins with programmable sink current, an 8-bit free-running timer, a watchdog timer, and Instant-On Now™ suspend wake-up capability.

Application Specific Microcontrollers Feature Summary

• Built-in 1.5-Mbps USB SIE compliant with USB Specification Version 1.1
• 8-bit RISC microcontroller with 35 USB-optimized instructions and Harvard architecture
• 4 Kbytes of EPROM program memory and 128 bytes of internal RAM
• Up to 16 GPIO pins with programmable pull-ups and sixteen-level sink current control

Application Specific Microcontrollers Applications

• Low-speed USB mice
• USB joysticks
• USB gamepads

Application Specific Microcontrollers Procurement Notes

Verify that the -PC suffix corresponds to the 20-pin PDIP package as specified in the datasheet. Confirm the component is manufactured by Cypress Semiconductor Corporation or its successor entity, Infineon Technologies. Ensure the OTP nature of the memory is accounted for during design validation.

Application Specific Microcontrollers Selection Notes

Select this model when a self-contained USB solution for HID devices is required without external transceivers. The CY7C63001A variant provides 4 Kbytes of EPROM, whereas the CY7C63000A offers only 2 Kbytes. The -PC package designation indicates a 20-pin PDIP form factor suitable through-hole mounting.

Application Specific Microcontrollers Part Context

This component belongs to the CY7C63xxx family of USB microcontrollers from Cypress Semiconductor. The CY7C63001A specifically denotes the version with 4 Kbytes of EPROM. The -PC suffix identifies the physical package as a 20-pin Plastic Dual In-line Package (PDIP).

Application Specific Microcontrollers Replacement Considerations

The CY7C63000A-PC is a compatible alternative within the same family but contains only 2 Kbytes of EPROM instead of 4 Kbytes. Designers must verify that firmware size fits within the smaller memory footprint before substituting.
