1 PRODUCT OVERVIEW
PRODUCT OVERVIEW
SAM87 PRODUCT FAMILY
Samsung's SAM87 family of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide
range of integrated peripherals, and various mask-programmable ROM sizes. Important CPU features include:
— Efficient register-oriented architecture
— Selectable CPU clock sources
— Release by interrupt of Idle and Stop power-down modes
— Built-in basic timer circuit with watchdog function
A 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 six CPU clocks) can be assigned to
specific interrupt levels.
KS88C8316/C8324/P8324
The KS88C8316 microcontroller has 16 K bytes of on-chip program memory and the KS88C8324 has 24 K bytes.
Both chips have a 272-byte general-purpose internal register file. The interrupt structure has seven interrupt
sources with six interrupt vectors. The CPU recognizes six interrupt priority levels.
Using a modular design approach, the following peripherals were integrated with the SAM87 core to make the
KS88C8316/C8324/P8324 suitable for use in color television and other types of screen display applications:
— Four programmable I/O ports (26 pins total: 16 general-purpose I/O pins; 8 n-channel, open-drain output pins)
— 2 channel A/D converter (4-bit resolution)
— 14-bit PWM output (one channels: push-pull type)
— Basic timer (BT) with watchdog timer function
— One 8-bit timer/counter (T0) with interval timer
— One 8-bit general-purpose timer/counter (TA) with prescalers
— On-screen display (OSD) with a wide range of programmable features including halftone control signal output
The KS88C8316/C8324 are available in a versatile 42-pin SDIP package.
OTP
The KS88C8316/C8324 microcontroller is also available in OTP (One Time Programmable) version, KS88P8324.
KS88P8324 microcontroller has an on-chip 24K-byte one-time-programmable EPROM instead of masked ROM.
The KS88P8324 is comparable to KS88C8316/C8324, both in function and in pin configuration.
