AT90S1200A-4PI

The AT90S1200A-4PI is a low-power, high-performance 8-bit microcontroller (MCU) developed by Microchip Technology. It is based on the AVR enhanced RISC architecture and operates at a frequency of up to 4 MHz. The AT90S1200A-4PI is part of the AT90S1200 series, which is known for its small size, low power consumption, and cost-effectiveness.

Description:

The AT90S1200A-4PI is a surface-mount 8-pin PDIP (Platinum Dual In-Line Package) microcontroller. It features 1K bytes of in-system programmable Flash memory, 64 bytes of EEPROM, and 128 bytes of SRAM (Static Random-Access Memory). The device also includes 8 general-purpose I/O lines, 32 general-purpose working registers, and a watchdog timer.

Features:

1. 8-bit AVR RISC architecture with 16-bit wide registers for high code density and fast execution
2. Up to 4 MHz operating frequency
3. 1K bytes of in-system programmable Flash memory with read-while-write capability
4. 64 bytes of EEPROM
5. 128 bytes of SRAM
6. 8 general-purpose I/O lines with optional internal pull-up resistors
7. 32 general-purpose working registers
8. Watchdog timer with internal oscillator and external clock option
9. Two software selectable power saving modes: idle and power-down
10. Brown-out detection and reset
11. Programmable clock source with internal RC oscillator, crystal oscillator, or external clock source
12. In-circuit serial programming (ICSP) and serial debug wire (SDW) for programming and debugging

Applications:
