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 of Idle and Stop power-down modes by interrupt
— 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 of six CPU clocks) can be assigned to
specific interrupt levels.
KS88C8424/C8432/P8432 MICROCONTROLLERS
The KS88C8424 microcontroller has a 24-Kbyte on-chip program memory and the KS88C8432 has a 32-Kbyte.
Both chips have a 272-byte general-purpose internal register file. The interrupt structure has nine interrupt
sources with nine interrupt vectors. The CPU recognizes seven interrupt priority levels.
Using a modular design approach, the following peripherals were integrated with the SAM87 core to make the
KS88C8424/C8432/P8432 microcontrollers 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; 10 n-channel, open-drain
output pins)
— 4-bit resolution A/D converter (4 channels)
— 14-bit PWM output (Two channels: push-pull type, open-drain type)
— Basic timer (BT) with watchdog timer function
— One 8-bit timer/counter (T0) with interval timer and PWM mode
— 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 KS88C8424 and the KS88C8432 are available in versatile 42-pin SDIP package.
OTP
The KS88C8424/C8432 microcontrollers are also available in OTP (One Time Programmable) version, named
the KS88P8432. The KS88P8432 microcontroller has an on-chip 32-Kbyte one-time-programmable EPROM
instead of a masked ROM. The KS88P8432 is comparable to the KS88C8424/C8432, both in function and pin
configuration.
