KS57C3204

KS57C3204/P3204 PRODUCT OVERVIEW 1 OVERVIEW PRODUCT OVERVIEW The KS57C3204 single-chip CMOS microcontroller has been designed for high performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). With features such as LCD direct drive capability, 4-channel A/D converter, 24-bit AM/FM frequency counter and watch timer, the KS57C3204 offers an excellent design solution for a wide variety of applications that require LCD functions and audio applications. Up to 32 pins of the 64-pin QFP package, it can be dedicated to I/O. Five vectored interrupts provide fast response to internal and external events. In addition, the KS57C3204 's advanced CMOS technology provides for low power consumption and a wide operating voltage range. OTP The KS57C3204 microcontroller is also available in OTP (One Time Programmable) version, KS57P3204 . The KS57P3204 microcontroller has an on-chip 4-Kbyte one-time-programmable EPROM instead of masked ROM. The KS57P3204 is comparable to KS57C3204, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW KS57C3204/P3204 FEATURES Memory — 256 × 4-bit RAM — 4096 × 8-bit ROM I/O Pins — Input only: 8 pins — I/O: 16 pins — Output only: 8 pins sharing with segment driver outputs LCD Controller/Driver — Maximum 14-digit LCD direct drive capability — 28 segment and 4 common pins — Display modes: Static, 1/2 duty (1/2 bias) 1/3 duty (1/2 or 1/3 bias), 1/4 duty (1/3 bias) — Internal resistor circuit for LCD bias Osci...
