CY7C64113-PVC

Application Specific Microcontrollers Overview

The CY7C64113 is an 8-bit One Time Programmable (OTP) microcontroller designed for full-speed USB applications. It features a Harvard architecture with a 6-MHz external clock source, generating internal clocks of 12 MHz and 48 MHz via a PLL. The device includes 8 KB of PROM and 256 bytes of RAM. Key peripherals include four GPIO ports (P0–P3), a Hardware Assisted Parallel Interface (HAPI), an I2C-compatible controller, a 12-bit free-running timer, and a Watchdog Timer. Uniquely, the CY7C64113 integrates a DAC port with programmable current sink outputs. It operates within a voltage range of 4.0V to 5.5V DC and supports up to five user-configurable USB endpoints.

• Programmable DAC Port: Features four pins with individually programmable sink currents ranging from 0.2 mA to 16 mA typical.
• Hardware Assisted Parallel Interface (HAPI): Enables high-speed data transfer to external devices without heavy CPU overhead.
• Integrated Peripherals: Includes an I2C-compatible master/slave controller, a 12-bit free-running timer, and a Watchdog Timer.

Application Specific Microcontrollers Applications

• USB Human Interface Devices (HID) such as keyboards and mice
• USB mass storage devices
• Custom USB peripheral controllers requiring parallel interface support
• Embedded systems needing programmable current sinking for LED or sensor control

Application Specific Microcontrollers Procurement Notes

Verify package type and revision status before ordering. The CY7C64113 is available in a 48-pin SSOP package. Confirm that the specific part number suffix matches the required pinout and electrical characteristics. Check for end-of-life notices or obsolescence warnings from Cypress Semiconductor or Infineon Technologies, as this component was released in 2004.

Application Specific Microcontrollers Selection Notes

Select the CY7C64113 over the CY7C64013 if the application requires the DAC port for programmable current sinking. Ensure the design accommodates the 48-pin SSOP package constraints. Verify that the system power supply remains stable between 4.0V and 5.5V DC. Consider the 8 KB OTP memory limit for firmware size and the need for an external 6-MHz crystal oscillator.

Application Specific Microcontrollers Part Context

The CY7C64113 belongs to the Cypress CY7C64xxx series of USB microcontrollers. It is functionally similar to the CY7C64013 but adds the DAC port capability. This series was designed to simplify USB integration by providing optimized instruction sets and hardware interfaces like HAPI and I2C directly on-chip, reducing the need for external logic components.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official Infineon/Cypress replacement guides or contact manufacturer support for cross-reference information due to the age of the product line.

Application Specific Microcontrollers FAQ

What is the maximum sink current for the DAC pins?

The DAC pins on the CY7C64113 have a programmable sink current range of 0.2 mA to 1.0 mA typical for standard operation, and up to 3.2 mA to 16 mA typical when configured for high-current output modes.

How many USB endpoints does the CY7C64113 support?

The device supports up to five user-configurable endpoints, which can be arranged as up to four 8-byte data endpoints or up to two 32-byte data endpoints.

What is the purpose of the HAPI interface?

The Hardware Assisted Parallel Interface (HAPI) allows for efficient data transfer between the microcontroller and external devices using parallel signals, reducing the processing load on the CPU compared to software-driven parallel communication.
