Description

The S3C84A4/S3P84A4 single-chip microcontroller is fabricated using a highly advanced CMOS process. Its design is based on the powerful SAM88RC 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 784 bytes. A flexible yet sophisticated external interface is used to access up to 64-Kbytes of program and data memory. The S3C84A4/S3P84A4 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 SAM88RC modular design approach, the following peripherals were integrated with the SAM88RC CPU core, S3P84A4 specifications:

  - Three configurable 8-bit general I/O ports
  - One 5-bit general I/O ports
  - Two 8-bit timers with interval timer
  - Two 16-bit timers/counters with PWM operating modes 8-bit or capture modes
  - Voltage level detector circuit embedded.
  - Two embedded chip selection pins (CS0CS1) or normal I/O ports
  - Two programmable 8-bit PWM modules with corresponding output pins
  - A/D converter with 4 selectable input pins
