Overview

The LC62F0164A single chip microcontroller integrates 64K words (128K bytes) of Flash EEPROM for program and data storage, 1K words (2K bytes) of internal RAM, 2 sets of timers (can be used as four timers), 2 channels of serial interfaces. The SANYO original high speed 16 bit CPU core (SNAIL) is used in the chip.

The LC62F0164A operates on 100 nS cycle time and most of instructions are one-word/one -cycle. The special architecture of the SNAIL core realizes both high speed operation and efficient code side. The instruction set of the SNAIL is simplified by disposing the instructions that are not frequently used. Simplified instruction set realized small core size like 8 bit microcontrollers and high speed operation like high performance 16 bit or 32 bit RISC chip. The SNAIL CPU core comprises high speed multiplier. The multiplier executes 16×16->32 bits multiplication in two cycles.

The LC62F0164A has 1M bit Flash EEPROM for program and data storage. The contents of the Flash EEPROM can be written by three ways : parallel programming using EPROM programmer, on board programming using serial data input and data re-writing by program control. Using the data rewrite function by program control, the LC62F0164A can eliminate the external Flash EEPROM which is used in variety of applications.
