Datasheet Summary
Powered by GS/AI

The AT89LP51IC2-20AAU is an 8-bit microcontroller compatible with the 8051 architecture, featuring an enhanced design that allows for a throughput of up to 20 MIPS at a clock frequency of 20 MHz. It operates in a fully static mode from 0 Hz to 20 MHz and includes a 2-cycle hardware multiplier and a 16x16 multiply-accumulate unit. The device offers 256 bytes of internal RAM and supports up to 1152 bytes of expanded RAM, which can be configured in software. This microcontroller includes 24KB or 32KB of in-system programmable (ISP) flash program memory, with a write/erase endurance of 10,000 cycles. It features multiple peripheral interfaces, including three 16-bit enhanced timer/counters, seven 8-bit PWM outputs, and an enhanced UART with automatic address recognition. The device supports dual data pointers and has a four-level interrupt priority system. Operating voltage ranges from 2.4V to 5.5V, and it is rated for a temperature range of -40¬8C to 85¬8C. The AT89LP51IC2-20AAU is available in various package types, including 44-lead PLCC, VQFP, and PDIP, and provides up to 40 programmable I/O lines. It also includes features such as brown-out detection, power-on reset, and low power modes, making it suitable for a wide range of embedded applications.
