KS57C21632

KS57C21632/P21632 PRODUCT OVERVIEW 1 OVERVIEW PRODUCT OVERVIEW The KS57C21632 single-chip CMOS microcontroller has been designed for high performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). With an up-to-896-dot LCD direct drive capability, and flexible 8-bit timer/counters, the KS57C21632 offers an excellent design solution for a high-end LCD game. Up to 12 pins of the 100-pin QFP package can be dedicated to I/O. Seven vectored interrupts provide fast response to internal and external events. In addition, the KS57C21632's advanced CMOS technology provides for low power consumption. OTP The KS57C21632 microcontroller is also available in OTP (One Time Programmable) version, KS57P21632. KS57P21632 microcontroller has an on-chip 32 K-byte one-time-programmable EPROM instead of masked ROM. The KS57P21632 is comparable to KS57C21632, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW KS57C21632/P21632 FEATURES Memory 768 × 4-bit RAM (excluding LCD display RAM) 32,768 × 8-bit ROM Interrupts 12 I/O Pins I/O: 12 pins Memory-Mapped I/O Structure LCD Controller/Driver 56 segments and 16 common terminals (8, 12 and 16 common selectable) Capacitor bias for LCD output.
