EPF025A

Part Number:EPF025A

Overview

EPF025A is a low cost high performance Micro Controller with 128KB embedded Flash and USB OTG 1.1. The chip integrates 80515 core, 128KB embedded Flash, 256 + 4KB RAM, USB OTG 1.1, Timer, Watchdog Timer, Serial Port, 8-bit PWM, SPI, IIC, Fan Tachometers, 10-bit ADC, Remote Decoder, Keyboard Interrupt and GPIO in a single chip.

Features

•On-chip 80515 core with 128K bytes Flash, 256 bytes Direct RAM and 4K bytes on-chip auxiliary RAM
•Fast CPU rate (24Mhz). 41.6 ns for shortest instruction
•Programmable CPU clocks from 24 Mhz to 500 Khz
•Programmable crystal start-up cycles from 0 to 4096 cycles
•Supports Idle mode and Stop mode for power saving.
•Supports crystal/CPU wake-up from Stop mode
•Supports In Circuit Flash programming (ICP)
•Supports 8 external interrupts
•Supports keyboard interrupt on 8 GPIO pins.
•On-chip USB OTG 1.1 which supports end-pint 0, 1, 2 and 64-byte bulk transfer
•On-chip 4 Timers supporting Timer, Pulse Output, Event Counter and Pulse Width Measurement modes
•Support primary and secondary crystal clock selection for Timer
•On-chip 15-bit programmable Watchdog Timer
•On-chip Serial Port which supports Synchronous mode and 8/9-bit UART modes
•On-chip 2 ports of Serial Peripheral Interface (SPI) supporting both Master and Slave modes
•On-chip 8 channels of 8-bit PWM with programmable repetition rate
•On-chip 2 channels of Fan Tachometers
•On-chip 8 channels of 10-bit ADC
•On-chip 2 IIC Master and 2 IIC Slave ports with configurable pin outs
•On-chip Consumer Infra-Red Remote Receiver (CIR) which supports NEC and Phillips RC-5/RC-6 protocols
•Support 11 General Purpose I/O Ports (total 85 I/O pins). Among them, 7 ports are open-drain programmable, two ports have 20 mA sink capability and 1 port (Port 9) supports By-Pass feature. All I/O ports are 5V tolerant.
•Timer, SPI, ADC and USB pins can be additional GPIO if the associated function is not enabled
•On-chip Low Voltage Inhibit (LVI) circuit which provides reliable power up reset and prevent accidental data loss in Flash
•Single 3.3V CMOS design
•128-pin LQFP package (Pb-Free)
