SM5907AF

compression and non compression type

shock-proof memory controller

Overview

- 2-channel processing

- Serial data input

⋅ 2s complement, 16-bit/MSB first, right-justified

format

⋅ Wide capture function

(up to 3

× speed input rate)

- System clock input

⋅ 384fs (16.9344 MHz)

- Shock-proof memory controller

⋅ ADPCM compression method

⋅ 4-level compression mode selectable

4-bit compression mode 2.78 s/Mbit

5-bit compression mode 2.22 s/Mbit

6-bit compression mode 1.85 s/Mbit

Full-bit non compression mode 0.74 s/Mbit

⋅ 4 external DRAM configurations selectable

1 or 2

× 16M DRAM (4M × 4 bits, refresh

cycle = 2048 cycle)

1 or 2

× 4M DRAM (1M × 4 bits)

- Microcontroller interface

⋅ Serial command write and status read-out

⋅ Data residual detector:

15-bit operation, 16-bit output

⋅ Forced mute

- Extension I/O

Microcontroller interface for external control

using 5 extension I/O pins

- +2.4 to +3.6 V operating voltage range

- Schmitt inputs

All input pins (including I/O pins) except CLK

(system clock)

- Reset signal noise elimination

Approximately 3.8

µs or longer (65 system

clock pulses) continuous LOW-level reset

- 44-pin QFP package (0.8 mm pin pitch)

The SM5907AF is a compression and non com-

pression type shock-proof memory controller LSI for

compact disc players. The compression level can

be set in 4 levels, and external memory can be

selected from 4 options (4M, 4M

× 2, 16M, 16M× 2).

It operates from a 2.4 to 3.6 V supply voltage

range.
