LC83010N, 83010NE
SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
O1001TN (KT)/N251JN KI No.3945–1/18
Overview
The LC83010N, 83010NE is a single-chip digital signal
processor (DSP). It is designed for use in the application
fields such as a digital processing of audio signals.
The LC83010N, 83010NE CMOS processor has various
on-chip filtering circuits such as a graphic equalizer for
reproduction of sound quality. It also has simulation cir-
cuit for reverberation (sound reflection and echo), so that
sound field with surround and delay can be created.
The LC83010N and LC83010NE are upgraded versions of
the LC83010 and the LC83010E. The LC83010N and
LC83010NE have a 64fs clock output that enables improved
interfacing with external A/D converters. TEST5 has been
renamed FS640/T5 and incorporates both the new clock
output and the original test output.
Features
LSI functions
Dual Harvard Architecture: Enables simultaneous pro-
cessing (multiply and addition) of stereo signals in a single
instruction cycle.
The LC83010N, LC83010NE processor has the follow-
ing two independent units:
Multiplier : 24 bits
× 16 bits (fixed-point decimal)
ALU : 32-bit arithmetic calculation, 24-bit arithmetic
and logical operations.
ACCumulator (ACC) : 32 bits
Temporal Registers (TMP0 to TMP7) : 32-bit for each
Internal Memory Data RAM
128
× 24 bits
Coefficient RAM
256
× 16 bits

ns or lower.
Serial input/output interface with a microcomputer.
Synchronous 8-bit serial input : 1
[Mail box (16 bits
× 8) function available]
Synchronous 8-bit serial output : 1
Interrupt function (Vectored interrupt with the INT pin)
Stack Nesting Levels : 4
On-chip Interval Timer :
12 bits (timer clock = sampling frequency)
Cycle time : 108ns (sampling frequency = 48kHz)
Single 5V power supply.
Package :
64-pin DIPs (LC83010N).
80-pin QFPs (LC83010NE).
Note) When soldering QFP devices, do not use the solder
dip method.
