N79E845/844/8432 Data Sheet
1 General Description
The N79E845/844/8432 8-bit Turbo 51 (4T Mode) microcontroller is embedded with 16K[1]/8K/4K bytes Flash EPROM
which can be programmed through universal hardware writer, serial ICP (In Circuit Program) programmer, software ISP
function. The instruction sets of the N79E845/844/8432 is fully compatible with the standard 8052. The
N79E845/844/8432 contains 16K/8K/4K bytes Application Flash EPROM (APROM) memory, 4 Kbytes Data Flash
memory, and 2 Kbytes Load Flash EPROM (LDROM) memory; 256 bytes direct and indirect RAM, 256 bytes XRAM;
17 I/O with bit-addressable I/O ports; two 16-bit timers/counters; 7-channel multiplexed 10-bit A/D converter; 4-channel
10-bit PWM; three serial ports including a SPI, I2C and an enhanced full duplex serial port; 2-level BOD voltage detec-
tion/reset, and power-on reset (POR). The N79E845/844/8432 also supports internal RC oscillator at the nominal frequen-
cy of 22.1184 MHz. The accuracy of RC oscillator (22.1184 MHz) is trimmed as ±1% under the condition of room tem-
perature and VDD = 5V before shipping from by factory trimming mechanism, which peripherals are supported by 14
sources of four-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the
N79E845/844/8432 allows the program memory to be programmed and read electronically. Once the code is confirmed,
the user can protect the code for security.
The N79E845/844/8432 microcontroller, featuring wide operating voltage range, built-in rich analog and digital periph-
erals and non-volatile Flash memory, is widely suitable for general control and home appliances.
[1] For N79E845, Data Flash and APROM share 16 Kbytes space.
