Introduction

AI Translation

The N79E825 series are an 8-bit Turbo 51 microcontroller which has an in-system programmable Flash EPROM which Flash EPROM can program by ICP (In Circuit Program) or by hardware writer. The instruction set of the N79E825 series are fully compatible with the standard 8052. The N79E825 series contain a 16K/8K/4K/2K bytes of main Flash EPROM; a 256 bytes of RAM; 256 bytes NVM Data Flash EPROM; two 8-bit bi-directional, one 2-bit bi-directional and bit-addressable I/O ports; two 16-bit timer/counters; 4-channel multiplexed 10-bit A/D convert; 4-channel 10-bit PWM; two serial ports that include a I2C and an enhanced full duplex serial port. These peripherals are supported by 13 sources four-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the N79E825 series allow the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
