N76E003 Datasheet
1. GENERAL DESCRIPTION
The N76E003 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 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 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 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 I C, 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 kHz 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 brown-out detection, which
stabilizes the power-on/off sequence for a high reliability system design.
The N76E003 microcontroller operation consumes a very low power with two economic power modes
to reduce power consumption － Idle and Power-down mode, which are software selectable. Idle
mode turns off the CPU clock but allows continuing peripheral operation. Power-down mode stops the
whole system clock for minimum power consumption. The system clock of the N76E003 can also be
slowed down by software clock divider, which allows for a flexibility between execution performance
and power consumption.
With high performance CPU core and rich well-designed peripherals, the N76E003 benefits to meet a
general purpose, home appliances, or motor control system accomplishment.
