Overview

The LC723780 Series are large-capacity ETR microcontrollers that can support up to 128KB of ROM and up to 8KB of RAM. In addition to the expanded table reference instruction to support large-capacity program ROM, the LC723780 Series provide enhanced interrupt capability to directly control CD mechanism and CD-DSP, and the capability to support the RDS models. They also have a built-in serial I/O port and an 8-input 8-bit A/D converter for communicating with the internal and external devices, and for minimizing the connecting wire between the front panel board and the main board, particularly for car audio systems.

The on-chip high-performance PLL circuit provides a high-speed lock circuit used to search for alternative frequencies of RDS in a short time, the ability to control the C/N characteristics of a local oscillator, and the high S/N through the direct PLL configuration.
