S3P9404

The S3C9404/C9414/S3P9404 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built naround the powerful SAM87Ri CPU core. The S3C9404/C9414/S3P9404 is a versatile microcontroller, with its A/D converter and a zero-crossing detection capability 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 S3C9404/C9414/S3P9404 has 4-Kbytes of program memory on-chip (ROM) and 208-bytes of general purpose register area RAM.

Using the SAM87Ri design approach, the following peripherals were integrated with the SAM87Ri core, S3P9404 specifications:

  - Four configurable I/O ports (S3C9404: 22 pins, S3C9414: 16 pins)
  - Six interrupt sources with one vector and one interrupt level
  - Two 8-bit timer/counter with various operating modes
  - Analog to digital converter (S3C9404: 8-bit, 8-channel, S3C9414: 10-bit, 5-channel)
  - One zero cross detection module

The S3C9404/C9414/S3P9404 microcontroller is ideal for use in a wide range of electronic applications requiring simple timer/counter, PWM, ADC, ZCD and capture functions. S3C9404 is available in a 30-pin SDIP and a 32-pin SOP package. S3C9414 is available in a 24-pin SDIP and a 24-pin SOP package.
