Overview
S3C8639/C863A/P863A PRODUCT OVERVIEW 1 PRODUCT OVERVIEW SAM8 PRODUCT FAMILY Samsung's SAM8 family of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU with a wide range of integrated peripherals, in various mask-programmable ROM sizes.
Analog its major CPU features are: — Efficient register-oriented architecture — Selectable CPU clock sources — Idle and Stop power-down mode release by interrupt — Built-in basic timer with watchdog function The sophisticated interrupt structure recognizes up to eight interrupt levels.
Each level can have one or more interrupt sources and vectors.
Fast interrupt processing (within a minimum of four CPU clocks) can be assigned to specific interrupt levels.
S3C8639/C863A/P863A MICROCONTROLLERS S3C8639/C863A/P863A single-chip 8-bit microcontrollers are based on the powerful SAM8 CPU architecture.
The internal register file is logically expanded to increase the on-chip register space.
S3C8639/C863A/P863A contain 32/48 Kbytes of onchip program ROM.
In line with Samsung's modular design approach, the following peripherals are integrated with the SAM8 core: — Four programmable I/O ports (total 27 pins) — One 8-bit basic timer for oscillation stabilization and watchdog functions — One 8-bit general-purpose timer/counter with selectable clock sources — One interval timer OTP S3C8639/C863A microcontrollers are also available in OTP (One Time Programmable) version named, S3P863A.
S3P863A microcontroller has an on-chip 48-Kbyte one-time-programmable EPROM instead of masked ROM.
S3P863A is comparable to S3C8639/C863A, both in function and pin configuration except its ROM size.
— One 12-bit counter with selectable clock sources, including Hsync or Csync input — PWM block with seven 8-bit PWM circuits — Sync processor block (for Vsync and Hsync I/O, Csync input, and Clamp signal output) — DDC Multi-master and slave-only IIC-Bus — 4-channel A/D converter (8-bit resolution) S3C8639/C863A/P863A are a versatile microcontrollers...
