XC17128EPD8C

XC17128EPD8C is an 8-bit microcontroller in the XC17x/8051‑class family. It’s intended for embedded control tasks and combines on‑chip program memory with RAM, I/O, and a range of peripherals. Typical features in this family include:
- 8051‑compatible CPU
- On‑chip Flash program memory and RAM
- Multiple I/O ports
- Timers and PWM
- Serial interfaces (UART/USART) and often SPI/I2C
- Optional ADC/DAC peripherals
- In‑system programming support and various low‑power modes
The EPD8C suffix generally denotes packaging, temperature grade, or revision and can vary by device. For exact specs (memory size, clock speed, voltage range, pin count, and peripheral set), consult the vendor’s datasheet or product brief for XC17128EPD8C. If you share the supplier link, I can summarize the precise details.

Pin count: 28 pins (package varies: DIP/SOIC).
Function: 8-bit microcontroller core (XC17128 family) with on-chip program memory and RAM plus common embedded peripherals (timers, I/O, serial interfaces). Exact features depend on package/revision; see the datasheet for specifics.

Manufacturer: Xicor, Inc.
What kind of company: A semiconductor company that designed and produced memory integrated circuits (nonvolatile RAM/EPROM). Xicor was later acquired by Intersil and is now part of Renesas Electronics.

Applications: Non-volatile memory for embedded systems. Typical uses include firmware storage (boot code and application code) and parameter/config data. Suitable for automotive ECUs, industrial controllers and PLCs, consumer electronics (set-top boxes, digital cameras, audio/video devices), telecom equipment, data loggers, medical devices, and portable peripherals.
