AT90S1200-4SI

The AT90S1200-4SI is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture from Microchip Technology. It features 1KB of in-system programmable Flash memory, 64 bytes of EEPROM, and 32 general-purpose working registers. The device includes an 8-bit timer/counter, on-chip analog comparator, programmable watchdog timer, and SPI interface for in-system programming. With 15 programmable I/O lines, it is suitable for a variety of embedded control applications. The microcontroller operates at a maximum clock frequency of 4 MHz and supports a supply voltage range of 2.7V to 6V. Power consumption is low: 2.0 mA active, 0.4 mA idle, and less than 1 µA in power-down mode at 3V and 4 MHz. The device is available in a 20-pin SOIC surface-mount package (20-SOIC) with an operating temperature range of -40°C to 85°C. The AT90S1200-4SI is ideal for applications requiring low power and moderate processing capability, such as consumer electronics, industrial control, and sensor interfaces.
