S3C9434

The S3C9432/S3C9434 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built around the powerful SAM87Ri CPU core. The S3C9432/S3C9434 is a versatile microcontroller, with its A/D converter, timer, PWM, and SIO it can be used in a wide range of general purpose applications.

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 S3C9432/S3C9434 have 2K-bytes or 4Kbytes of program memory on-chip (ROM) and 112-bytes of general purpose register area RAM.

Using the SAM87Ri design approach, the following peripherals were integrated with the SAM87Ri core, S3C9434 specifications:

  - Three configurable I/O ports (13 pins)
  - Five interrupt sources with one vector and one interrupt level
  - One 8-bit timer/counter with time interval mode
  - Analog to digital converter with five input channels and 10-bit resolution
  - One synchronous SIO module
  - One 12-bit PWM output

The S3C9432/S3C9434 microcontroller is ideal for use in a wide range of electronic applications requiring simple timer/counter, PWM, ADC, and SIO. S3C9432/S3C9434 is available in a 20/18/16-pin DIP and a 20-pin SOP package.
