KS57C2916/P2916 MICROCONTROLLER PRODUCT OVERVIEW

1 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.

KS57C2916/P2916 MICROCONTROLLER KS57P2916 OTP

15 KS57P2916 OTP

OVERVIEW

The KS57P2916 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the

KS57C2916 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by
serial data format.

The KS57P2916 is fully compatible with the KS57C2916, both in function and in pin configuration. Because of its
simple programming requirements, the KS57P2916 is ideal for use as an evaluation chip for the KS57C2916.

OPERATING MODE CHARACTERISTICS

When 12.5 V is supplied to the VPP(TEST) pin of the KS57P2916, the EPROM programming mode is entered.
The operating mode (read, write, or read protection) is selected according to the input signals to the pins listed in

Table 15–3 below.
