OVERVIEW
PRODUCT OVERVIEW
The KS57C21408/C21418/P21408 is a SAM47 core-based 4-bit CMOS single-chip microcontroller. It has a timer/counter and LCD drivers. The KS57P21408 is especially suited for use in data bank, telephone and LCD general purpose. It is built around the SAM47 core CPU and contains ROM, RAM, 39 I/O lines, programmable timer/counter, buzzer output, enough LCD dot matrix, and segment drive pins. The KS57C21408/C21418/P21408 can be used for dedicated control functions in a variety of applications, and is especially designed for multi data bank, telephone and LCD game.
OTP
The KS57C21408/C21418 microcontroller is also available in OTP (One Time Programmable) version, KS57P21408. KS57P21408 microcontroller has an on-chip 8 K-byte one-time-programable EPROM instead of masked ROM. The KS57P21408 is comparable to KS57C21408/C21418, both in function and in pin configuration.

OVERVIEW
KS57P21408 OTP
The KS57P21408 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the KS57C21408/C21418 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by serial data format. The KS57P21408 is fully compatible with the KS57C21408/C21418, both in function and in pin configuration. Because of its simple programming requirements, the KS57P21408 is ideal for use as an evaluation chip for the KS57C21408/C21418.

Table 15-1. Descriptions of Pins Used to Read/Write the EPROM Main Chip Pin Name P3.1 Pin Name SDAT Pin No. 13 During Programming I/O I/O Function Serial data pin. Output port when reading and input port when writing. Can be assigned as a Input / push-pull output port. Serial clock pin. Input only pin. Power supply pin for EPROM cell writing (indicates that OTP enters into the writing mode). When 12.5 V is applied, OTP is in writing mode and when 5 V is applied, OTP is in reading mode. (Option) Chip initialization Logic power supply pin. VDD should be tied to +5 V during programming.
