LC72F3661
Overview
The LC72F3661 is a ETR controller with an on-chip one-time PROM for use with the LC723661, 3662, and 3663 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 64Kbytes (32K
× 16 bits).
Functions
• ROM
: Up to 32K steps (32767
×16-bits)
The subroutine area holds 4K steps (4,096
×16-bits)
• RAM
: Up to 8K
×4-bits (In banks 00 through 7F)
• Stack
: 32 levels
• Serial I/O
: Two 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
: Five interrupt inputs (pins INT0, 1, 4, and 5, 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
: Six interrupts ; four internal timer interrupts, and two serial I/O interrupts.
Ordering number : EN*A0461A
