The S3C9644/S3C9648/P9648 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built around the powerful SAM87RI 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 S3C9644 has 4K-bytes of program memory on-chip and S3C9648 has 8K-bytes.
Using the SAM87RI design approach, the following peripherals were integrated with the SAM87RI core, S3C9648 specifications:
- Five configurable I/O ports (32 pins)
- 20 bit-programmable pins for external interrupts
- 8-bit timer/counter with three operating modes
- Low speed USB function
The S3C9644/S3C9648/P9648 is a versatile microcontroller that can be used in a wide range of low speed USB support general purpose applications. The S3C9648 is especially suitable for use as a keyboard controller and is available in a 42-pin SDIP and a 44-pin QFP package.
