1 PRODUCT OVERVIEW
PRODUCT OVERVIEW
OVERVIEW
The KS57C2916 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-704-dot LCD direct drive capability, and flexible 8-bit timer/counter, the KS57C2916 offers an
excellent design solution for a mid-end LCD game.
Up to 8 pins of the 80-pin QFP package can be dedicated to I/O. Six vectored interrupts provide fast response to
internal and external events. In addition, the KS57C2916's advanced CMOS technology provides for low power
consumption.
OTP
The KS57C2916 microcontroller is also available in OTP (One Time Programmable) version, KS57P2916.
KS57P2916 microcontroller has an on-chip 16K-byte one-time-programable EPROM instead of masked ROM.
The KS57P2916 is comparable to KS57C2916, both in function and in pin configuration.
