Microchip Technology, Inc. Microcontrollers AT89LP828-20MH

The AT89LP828-20MH is an 8-bit microcontroller from Quarktwin Technology Ltd., designed to be compatible with MCS¬Æ51 products. It features an enhanced 8051 architecture that allows for a throughput of up to 20 MIPS at a clock frequency of 20 MHz. The microcontroller operates fully statically from 0 Hz to 20 MHz and includes a 2-cycle hardware multiplier. This device offers nonvolatile program and data memory with options for 4K or 8K bytes of in-system programmable (ISP) Flash program memory and 512 or 1024 bytes of Flash data memory, both with a minimum endurance of 100,000 write/erase cycles. It supports a serial interface for program downloading and includes a fast page programming mode. The AT89LP828-20MH is equipped with various peripheral features, including three 16-bit enhanced timer/counters, two 8-bit PWM outputs, and an enhanced UART with automatic address recognition. It also has dual analog comparators, a programmable watchdog timer, and multiple general-purpose interrupt pins. Operating conditions for this microcontroller range from 2.4V to 5.5V with a temperature range of -40¬8C to 85¬8C. It is available in multiple package types, including 28-lead PDIP and 32-lead TQFP, providing flexibility for different design requirements.
