The 32-pin S3F8S39 MCU is a member of Zilog's S3F8 Series of S3 MCUs, and offers a fast and efficient Z8-compatible CPU, 32KB of Flash memory, and a wide range of integrated peripherals.

Its CPU features an efficient register-oriented architecture and a sophisticated interrupt controller allowing for fast context switching. Flash memory is CPU-programmable and has a 128-byte sector size. The internal oscillator is switchable between 8MHz, 4MHz, 1MHz and 0.5MHz for low-power applications.

Four 16-bit timers with PWM and pulse generation make this device ideal for controlling load power in heating and motor control applications in home appliances. The timers can also be configured for carrier generation in IR remote control applications.

The S3F8S39 MCU is offered in the following 4 package types:

• 32-pin SOP

• 32-pin SDIP

• 32-pin ELP

• Pellet (Die)
