Ordering number : EN*A0461A LC72F3661 Overview CMOS IC Electronic tuning radio for car audio ETR Controller 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 RAM Stack Serial I/O : Up to 32K steps (32767×16-bits) The subroutine area holds 4K steps (4,096×16-bits) : Up to 8K×4-bits (In banks 00 through 7F) : 32 levels : 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 : 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. : Six interrupts ; four internal timer interrupts, and two serial I/O interrupts.
