LC89170M
CD Player Text Data IC
Preliminary
Overview
The LC89170M is an IC that decodes the text data, such
as song names, stored in subcode channels R to W of a
compact disk’s read-in area.
Features
• Accepts the channel R to W subcode data through a
subcode interface.
• Can continuously output the channel R to W data for
each 1PACK24 symbol.
• Performs error detection (cyclic redundancy code) and
outputs both the data and the result of that check.
• Provides synchronization protection for the subcode
interface.
• Supports low-voltage operation (3.3 V)
• Provided in the miniature MFP-14S package.

• Microcontroller interface
The LC89170M includes a 32-word × 8-bit dual-port RAM on chip, and the 1PACK 24 symbols from subcode channels
R to W can be read out once every 3.3 ms (or once every 1.66 for double-speed playback) over the microcontroller
interface. Figure 3 shows the timing.
Figure 3 Microcontroller Interface Output Timing
The 1PACK 24 symbols for the subcode R to W data (18 bytes) are entered into the dual-port RAM and input to the CRC
checking circuit. After the data for 1 PACK has all been input, a falling edge is output from the DQSY pin and the CRC
flags are output from SRDT. A high is output for the CRC flags if the check returned OK. Next, 128 bits of data are
output by inputting the SCLK clock signal. A single packet of data is output by repeating this operation four times.
