Summary

3826 Group (One Time PROM version) Datasheet

A - 1

1.00 Sep 06, 2006

First edition issued

This datasheet describes only 3826 Group One Time PROM version (60K version

of ROM).

The change point from past 3826 Group datasheet (MEJ02B0083-0102Z) is de-

scribed to the revision history as your information though it is a first edition.

Improvement term union of sentence expressions.

Terms are united. (Union terms: A/D converter, D/A converter, serial interface, etc.)

Package type: 100P6S-A → PRQP0100JB-A, 100P6Q-A → PLQP0100KB-A

DESCRIPTION: Revised for One Time PROM and EPROM vertions.

FEATURES: Power source voltage, power dissipation reviced and 10-bit A/D mode

added.

APPLICATIONS: cordless phone, wireless application, household appliances,

added

Fig. 58 AD conversion low-order register (001416) added.

CLOCK GENERATING CIRCUIT: Underline part changed and ( ) added

A feed-back resistor exists on-chip (An external feed-back resistor may be needed

depending on conditions.). However, an external feed-back resistor is needed be-

tween XCIN and XCOUT since a resistor does not exist between them.
