N76E003AQ20 IC MCU 8BIT 18KB FLASH 20QFN

The N76E003 is an embedded flash type, 8-bit high performance 1T 8051-based microcontroller. Theinstruction set is fully compatible with the standard 80C51 and performance enhanced.The N76E003 contains a up to 18K Bytes of main Flash called APROM, in which the contents of User Coderesides. The N76E003 Flash supports In-Application-Programming (IAP) function, which enables on-chipfirmware updates. IAP also makes it possible to configure any block of User Code array to be used as nonvolatile data storage, which is written by IAP and read by IAP or MOVC instruction. There is an additional Flashcalled LDROM, in which the Boot Code normally resides for carrying out In-System-Programming (ISP). TheLDROM size is configurable with a maximum of 4K Bytes. To facilitate programming and verification, the Flashallows to be programmed and read electronically by parallel Writer or In-Circuit-Programming (ICP). Once thecode is confirmed, user can lock the code for security.The N76E003 provides rich peripherals including 256 Bytes of SRAM, 768 Bytes of auxiliary RAM (XRAM), Upto 18 general purpose I/O, two 16-bit Timers/Counters 0/1, one 16-bit Timer2 with three-channel input capturemodule, one Watchdog Timer (WDT), one Self Wake-up Timer (WKT), one 16-bit auto-reload Timer3 forgeneral purpose or baud rate generator, two UARTs with frame error detection and automatic addressrecognition, one SPI, one I2C, five enhanced PWM output channels, eight-channel shared pin interrupt for allI/O, and one 12-bit ADC. The peripherals are equipped with 18 sources with 4-level-priority interruptscapability.
