N76E616AL48

The N76E616 is an embedded flash type, 8-bit high performance 1T 8051-based microcontroller. The instruction set is fully compatible with the standard 80C51 and performance enhanced.

The N76E616 contains an up to 18K Bytes of main Flash called APROM, in which the contents of User Code reside. The N76E616 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 non-volatile 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 N76E616 provides rich peripherals including 256 Bytes of SRAM, 256 Bytes of auxiliary RAM (XRAM), up to 46 general purpose I/O, two 16-bit Timers/Counters 0/1, one 16-bit Timer 2 group with four auto-reload or PWM timers, one Watchdog Timer (WDT), one Self Wake-up Timer (WKT), one 16-bit auto-reload Timer 3 for general purpose or baud rate generator, two UARTs with frame error detection and automatic address recognition, one I²C, eight-channel shared pin interrupt for all I/O, one 10-bit ADC, and the LCD driver for up to 180 pixels. The peripherals are equipped with 17 sources with 4-level-priority interrupts capability.

The N76E616 is equipped with five clock sources and supports switching on-the-fly via software. The four clock sources include 2 MHz to 16 MHz high-speed external crystal/resonator, 32.768 kHz lowspeed external crystal/resonator, external clock input, 10 kHz internal oscillator, and one 11.059 MHz internal precise oscillator that is factory trimmed to ±1% at room temperature.
