ATMEL 8-Bit 8051 Flash Microcontroller SMD
Low-power ATMEL 8-bit 8051 microcontroller with 20KB flash memory, 256-byte RAM, and 44-pin SMD package. Ideal for embedded design.
The ATMEL 8-bit 8051 Flash Microcontroller is a low-power, high-performance CMOS microcontroller featuring 20kB of flash programmable read-only memory and 256 bytes of RAM. Manufactured using high-density nonvolatile memory technology, this device is fully compatible with the industry-standard 80C51 and 80C52 instruction sets and pinouts. The on-chip flash allows the program memory to be easily programmed by a conventional nonvolatile memory programmer.
By combining a versatile 8-bit CPU with flash on a monolithic chip, this microcontroller provides a highly flexible and powerful solution for various computing needs. It is fully compatible with MCS-51 products and boasts an impressive 10,000 write/erase cycles endurance. Operating at a fully static frequency of 0 to 33MHz, it ensures reliable performance across diverse environments.
This device is equipped with a three-level program memory lock, 32 programmable I/O lines, three 16-bit timers/counters, and eight interrupt sources. Additional features include a programmable serial channel, low-power idle and power-down modes, and interrupt recovery from power-down mode. It also incorporates a hardware watchdog timer, a dual data pointer, and a power-off flag for enhanced operational control.
Housed in a 44-pin LCC surface-mount package, it operates efficiently within a supply voltage range of 4V to 5.5V and an operating temperature range of -40°C to 85°C. The product dimensions are 43 mm in height, 33 mm in width, and 15 mm in depth, with a lightweight profile of just 0.2 grams.
