S3P8454

The S3P8454 single-chip microcontroller is fabricated using a highly advanced CMOS process. Its design is based on the powerful SAM87RC CPU core. Stop and Idle power-down modes were implemented to reduce power consumption. The size of the internal register file is logically expanded, increasing the addressable on-chip register space to 1040 bytes. A flexible yet sophisticated external interface is used to access up to 64-Kbytes of program and data memory. The S3P8454 is a versatile microcontroller that is ideal for use in a wide range of general-purpose applications such as CD-ROM/DVD-ROM drives.

Using the SAM87RC modular design approach, the following peripherals were integrated with the SAM87RC CPU core, S3P8454 specifications:

  - Five configurable 8-bit general I/O ports
  - One 2-bit general I/O ports
  - Full-duplex serial data port with one synchronous operating modes
  - Two 8-bit timers with interval timer
  - Two 16-bit timers/counters with PWM operating modes or capture modes
  - One voltage level detector pin
  - Four embedded chip selection pins (CS0CS4) or normal I/O ports
  - Two programmable 8-bit PWM modules with corresponding output pins
  - A/D converter with 4 selectable input pins
