LC72F3781
Overview
The LC72F3781 is a ETR controller with an on-chip one-time PROM for use with the LC723781N, 2N, 3N, 4 and 5
mask versions. Since it has the equivalent electrical performance, pin layout and package as these mask versions, it is
ideally suited for checking program operations, starting the initial shipment of finished products and reducing the
switchover time frame when specifications are changed.
The PROM size is 128 Kbytes (64K
× 16 bits).
Functions
ROM
: Up to 64K steps (65,535
×16-bits)
The subroutine area holds 4K steps (4,096
×16-bits)
RAM
: Up to 16K
×4-bits (In banks 00 through FF)
Stack
: 32levels
Serial I/O
: Three channels. These circuits can support both 2-wire and 3-wire 8-bit communication
techniques, and can be switched between MSB first and LSB first operation.
One of six internally generated serial transfer clock rates can be selected: 12.5kHz,
37.5kHz, 187.5kHz, 281.25kHz, 375kHz, and 450kHz
External interrupts
: Seven interrupt inputs (pins INT0 through INT5, and the HOLD pin)
These interrupts can be set to switch between rising and falling edges, although the HOLD
pin only supports falling edge detection.
Internal interrupts
: Seven interrupts ; four internal timer interrupts, and three serial I/O interrupts.
Ordering number : EN*A0459A
