Overview
The LC8954 is an error correction and AD PCM decoder LSI for CD-I applications, and integrates in a single chip selected functions from the Sanyo LC8951, LC8955 and LC8953 products. Of the hardware required for CD-I applications, the LC8954 integrates all of the CD player output peripheral circuits in a single chip.

Features
• Can be directly connected to a 68000 CPU.
• Built-in DMA controller interface
• Built-in APU circuit that supports independent gain settings in four channels
• Can be directly connected to the Sanyo LC78835 and LC78835M (digital filter and D/A converter)
• Features from the LC8951 and LC8955 are inherited by the LC8954.
• Subcode interface on-chip
• External SRAM access from sub-CPU
• CMOS single voltage power supply: 5 V
• By combining features from the LC8951, LC8955, and portions of theLC8953 into one chip, the peripheral section of a CD player within a CD-I system can be constructed with just one chip.
