N79E715 Datasheet
1 General Description
The N79E715 8-bit Turbo 51 (4T Mode) microcontroller is embedded with 16 Kbytes Flash EPROM
that can be programmed through universal hardware writer, serial ICP (In Circuit Program)
programmer, and software ISP function. The instruction sets of the N79E715 are fully compatible with
the standard 8052. The N79E715 contains 16 Kbytes [1] program memory (APROM) and 2 Kbytes
Load Flash EPROM (LDROM) memory, 256 bytes direct and indirect RAM, 256 bytes XRAM; 25 I/O
with bit-addressable I/O ports; two 16-bit timers/counters; 8-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 detection/reset and power-on reset (POR). The N79E715 also supports internal
RC oscillator 22.1184 MHz that is factory trimmed to ± 1% at room temperature and VDD = 5V.
These peripherals are supported by 14 sources of four-level interrupt capability. To facilitate
programming and verification, the Flash EPROM inside the N79E715 allows the program memory to
be programming and read electronically. The code is once confirmed. Thus the user can protect the
code for security.
The N79E715 microcontroller, featuring wide operating voltage range, built-in rich analog and digital
peripherals and non-volatile Flash memory, is widely suitable for general control and home
appliances.
