Product data

2.1 Key features

s Extended features of the 51MX Core:

x 23-bit program memory space and 23-bit data memory space

x Linear program and data address range expanded to support up to 8 Mbytes

each

x Program counter expanded to 23 bits

x Stack pointer extended to 16 bits enabling stack space beyond the 80C51

limitation

x New 23-bit extended data pointer and two 24-bit universal pointers greatly

improve C compiler code efficiency in using pointers to access variables in

different spaces

s 100% binary compatibility with the classic 80C51 so that existing code is

completely reusable

s Up to 24 MHz CPU clock with 6 clock cycles per machine cycle

s 96 kbytes of on-chip program Flash

s 2 kbytes of on-chip data RAM

s Programmable Counter Array (PCA)

s Two full-duplex enhanced UARTs

s Byte based Fast I2C serial interface (400 kbits/s)

2.2 Key benefits

s Increases program/data address range to 8 Mbytes each

s Enhances performance and efficiency for C programs

s Fully 80C51-compatible microcontroller

s Provides seamless and compelling upgrade path from classic 80C51

s Preserves 80C51 code base, investment/knowledge, and peripherals and ASICs

s Supported by wide range of 80C51 development systems and programming tools

vendors

s The P89C669 makes it possible to develop applications at lower cost and with a

reduced time-to-market

2.3 Complete features
