4-Bit Micro-Controller With EEPROM, 1K Word
Features
Very low current dissipation. Wide operating voltage range. Supports both Ag and Li batteries. Powerful instruction set. 4-level subroutine nesting (including interrupt). 4 event-driven interrupts, 2 external and 2 internal. ROM size: 1024x15 bits. RAM size: 64x4 bits. Input ports: 2 ports/ 8 pins (S and M). Output port: 1 port/ 4 pins (P). Pseudo serial output port (P). Input/Output ports: 2 ports/ 8 pins (I/OA and I/OB). Control outputs: ALARM, LIGHT. LCD driver outputs (can drive up to 75 LCD segments). PROM option to select 4 LCD drive modes: static, duplex (1/2 duty 1/2 bias, 1/3 duty 1/2 bias or 1/3 duty 1/3 bias). PROM option permits LCD driver output pins to be used for DC output ports; up to 25 pins are available. Segment PLA circuit permits any layout on LCD panel. Built-in clock generator (crystal or RC). Built-in voltage doubler, halver, tripler. Endurance: More then 100 write cycles/word. Security bit for read/write protection.
General Description
The JA54130 is an EEPROM-equipped high- performance 4-bit microcomputer. It contains not only all functions compatible with JA54100, but also an EEPROM, providing customers such conveniences as on-board verification, customized code, small quantity sample production, etc. This chip especially provides a security bit to protect the customer's code.
