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 which are ideal for use in multi-sync
monitors or in general-purpose applications that
require sophisticated timer/counter, PWM, sync
signal processing, A/D converter, and multi-master
IIC-bus support with DDC. They are available in a
42-pin SDIP or a 44-pin QFP package.
