Description

The S3P9234 can be used for dedicated control functions in a variety of applications, and is especially designed for application with FRS or etc.

The S3C9234/S3P9234 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built around the powerful SAM88RCRI CPU core.

Stop and Idle power-down modes were implemented to reduce power consumption. To increase on-chip register space, the size of the internal register file was logically expanded. The S3C9234/S3P9234 has 4K-byte of program ROM, and 208-byte of RAM (including 16-byte of working register and 16-byte LCD display RAM).

Using the SAM88RCRI design approach, the following peripherals were integrated with the SAM88RCRI core, S3P9234 specifications:

  - 7 configurable I/O ports including ports shared with segment/common drive outputs
  - 7-bit programmable pins for external interrupts
  - One 8-bit basic timer for oscillation stabilization and watch-dog functions
  - Two 8-bit timer/counters with selectable operating modes
  - Watch timer for real time
  - 8-bit serial I/O interface
