Features
The S3F8S28 MCU is member of Zilog's S3F8 Series of S3 MCUs, and offers a fast and efficient Z8-compatible CPU, 8KB of Flash memory, and a wide range of integrated peripherals.
The S3 Family CPU features an efficient register-oriented architecture and a sophisticated interrupt controller that allow for fast context switching. Flash memory is CPU-programmable and offers a 128-byte sector size. The internal oscillator is switchable between 8 MHz, 4 MHz, 2 MHz, 1 MHz, and 0.5 MHz for low-power applications. The 13-channel, 12-bit ADC and two 14-bit PWM modules make this device perfect for small appliance sensing applications such as ceiling fans, smoke detectors, PIR motion detectors, battery chargers, LED lighting control, and oven controllers.
Additional features including a UART, I2C master/slave and two 16-bit timers provide functions necessary for system expansion, board-level management and external communications.
The S3F8S28 MCU is offered in the following 6 package types:
20-pin DIP
20-pin SOP
20-pin SSOP
24-pin SOP
24-pin TSSOP
Pellet (Die)
