OVERVIEW
NuTiny-SDK-N76E885 is the specific development tool for 8-bit high performance 1T 8051-based
microcontroller N76E885 series. User can use NuTiny-SDK-N76E885 to develop and verify the
application program easily.
NuTiny-SDK-N76E885 includes two portions. One is NuTiny-EVB-N76E885 and the other is Nu-
Link-Me. NuTiny-EVB-N76E885 is the evaluation board and Nu-Link-Me is its Debug Adaptor.
Thus, user does not need other additional ICE or debug equipment.
The Nuvoton 1T 8051-based microcontroller N76E885 series is function compatible with the
N76E616 and N76E885 series, the 8-bit high performance 1T 8051-based microcontroller. The
instruction set is fully compatible with the standard 80C51 and performance enhanced. The
N76E885 series can bridge the gap and replace the cost equivalent to traditional 4T, 6T and 12T
8-bit microcontroller by 1T 8-bit high performance and rich functions. With high performance CPU
core and rich well-designed peripherals, the N76E885 benefits to meet a general purpose, home
appliances, or motor control system accomplishment.
The N76E885 series can run up to 16 MHz, and operate at a wide voltage range of 2.4V ~ 5.5V
and temperature range of -40
℃
~ +105
℃
. For the N76E885 series, the embedded program flash
size is up to 18 Kbytes, SRAM is 256 bytes, and 256 Bytes of auxiliary RAM (XRAM). The
N76E885 series also offers size configurable 4K/3K/2K/1K/0K bytes flash of LDROM for the ISP,
which provides flexibility to user developed Boot Code.
The N76E885 series has many high-performance peripheral functions, such as 22.1184 MHz
high-speed internal RC oscillator (trimmed to ±1% when VDD 5.0V, ±2% in all conditions), Up to
25 general purpose I/O pins and one input-only pin, four 16-bit timers, two full-duplex UARTs
ports with frame error detection and automatic address recognition, one SPI interface, one I

interface, up to five enhanced 16-bit PWM output channels, 8 channels 12-bit ADC, Watchdog
Timer, Self Wake-up Timer, and a Brown-out Detector. The peripherals are equipped with 18
sources with 4-level-priority interrupts capability. All these peripherals have been incorporated into
the N76E885 series to reduce component count, board space and system cost.
Additionally, the N76E885 series is equipped with ISP (In-System Programming) and ICP (In-
Circuit Programming) functions, which allow the user to update the program memory without
removing the chip from the actual end product. The N76E885 series also supports In-Application-
Programming (IAP) function, user switches the code executing without the chip reset after the
embedded flash updated.
