ATMEL 8-Bit 8051 Microcontroller, 4KB Flash, 20-Pin DIP
ATMEL 8-bit 8051 microcontroller with 4KB Flash, 128-byte RAM, 15 I/O lines, and UART. Ideal for industrial embedded control applications.
The ATMEL 8-Bit 8051 Microcontroller is a low-voltage, high-performance CMOS microcontroller featuring 4kB of flash programmable and erasable read-only memory. Manufactured using ATMEL's high-density non-volatile memory technology, this device is fully compatible with the industry-standard MCS-51 instruction set. By combining a versatile 8-bit CPU with flash on a monolithic chip, it provides a highly flexible solution to many embedded control applications.
Standard Features
- 4kB of reprogrammable flash memory with 10,000 write/erase cycles
- 128 bytes of internal RAM
- 15 programmable I/O lines
- Two 16-bit timer/counters
- Six interrupt sources with a two-level interrupt architecture
- Programmable serial UART channel (full duplex)
- Precision on-chip analogue comparator
- Direct LED drive outputs
- On-chip oscillator and clock circuitry
Power Management and Reliability
Designed with static logic for operation down to zero frequency, the microcontroller supports two software-selectable power-saving modes: low-power idle and power-down. It also features brown-out detection and power-on reset (POR) for reliable operation. The device operates at a maximum frequency of 24MHz with a supply voltage ranging from 2.7V to 6V. It comes in a 20-pin DIP through-hole package measuring 43 mm x 33 mm x 15 mm, weighing 227.3 grams.
