AT89C5131A-TIRUL  

Microcontrollers

The AT89C5131A-TIRUL is a low-power, high-performance CMOS 8-bit microcontroller unit (MCU) manufactured by Microchip Technology. It is based on the enhanced 8051 microarchitecture and is designed for a wide range of embedded control applications.

Description:

The AT89C5131A-TIRUL features 128K bytes of in-system programmable Flash memory, 4K bytes of SRAM, and 1K bytes of EEPROM. It operates with a single 8MHz to 32MHz crystal oscillator and can be powered by a wide range of supply voltages (2.7V to 6.0V). The device is available in a 100-pin TQFP package.

Features:

1. Enhanced 8051 microarchitecture with 128KB Flash memory, 4KB SRAM, and 1KB EEPROM.
2. In-system programmability and flash memory read-while-write capability.
3. 8MHz to 32MHz crystal oscillator frequency range.
4. Wide operating voltage range (2.7V to 6.0V).
5. 100-pin TQFP package.
6. On-chip debugging and in-application programming capabilities.
7. Low-power consumption with power-down and power-save modes.
8. 4-channel 16-bit timer/counter with watchdog timer and two 16-bit software timers.
9. 12-channel 10-bit A/D converter with up to 1Msps conversion rate.
10. 2-channel UART, one SPI, and one I2C for communication.
11. 8-bit programmable counter array (PCA) for event handling and PWM generation.
12. 16-bit automatic address increment for data space.
13. 64 interrupt sources with 5 priority levels.
14. On-chip voltage regulator and brown-out detection/reset.
15. Up to 33 general-purpose I/O pins, including 5 input-only pins for analog inputs.
