N76E003AS20 Datasheet | Nuvoton Technology

DESCRIPTION The N76E003 is an embedded flash type, 8-bit high performance 1T 8051-based microcontroller. The instruction set is fully patible 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 Code resides. The N76E003 Flash supports In-Application-Programming (IAP) function, which enables on-chip firmware 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 Flash called LDROM, in which the Boot Code normally resides for carrying out In-System-Programming (ISP). The LDROM size is configurable with a maximum of 4K Bytes. To facilitate programming and verification, the Flash allows to be programmed and read electronically by parallel Writer or In-Circuit-Programming (ICP). Once the code 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), Up to 18 general purpose I/O, two 16-bit Timers/Counters 0/1, one 16-bit Timer2 with three-channel input capture module, one Watchdog Timer (WDT), one Self Wake-up Timer (WKT), one 16-bit auto-reload Timer3 for general purpose or baud rate generator, two UARTs with frame error detection and automatic address recognition, one SPI, one I2C, five enhanced PWM output channels, eight-channel shared pin interrupt for all I/O, and one 12-bit ADC. The peripherals are equipped with 18 sources with 4-level-priority interrupts capability. The N76E003 is equipped with three clock sources and supports switching on-the-fly via software. The three clock sources include external clock input, 10 k Hz internal oscillator, and one 16 MHz internal precise oscillator that is factory trimmed to ±1% at room temperature. The N76E003 provides additional power monitoring detection such as power-on reset and 4-level...
