The 48-pin S3F8S19 MCU, a member of Zilog's S3F8 Series of S3 MCUs, offers a fast and efficient Z8 compatible CPU, 32 KB 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, 1 MHz, and 0.5 MHz for low-power applications. Four 16-bit timers with PWM and pulse generation make this device ideal for controlling load power in heating, motor control, and home appliance applications in which LCD panels are standard user interfaces.

The timers in this MCU can also be configured for carrier generation in IR remote control applications, while the on-chip LCD controller provides low-power display control.

The S3F8S19 MCU is offered in the following 2 package types:

• 48-pin QFP

• Pellet (Die)
