TC94A58FAG
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC94A58FAG
Single-Chip CD Processor with Built-in Controller
The TC94A58FAG is a single-chip CD processor for digital
servo, which incorporates a 4-bit microcontroller.
The controller features an LCD driver, 4-channel 6-bit AD
converter, 1 port 2-channel 2/3-line or UART serial interface
module, a buzzer, 20-bit general-purpose counter function,
interrupt function, and 8-bit timer/counter. The CPU can select
www.DataSheet4U.comone of four operating clocks (16.9344-MHz, 75-kHz or 32.768-kHz
crystal oscillator and external clock input), facilitating interface
with the CD processor.
The CD processor incorporates sync separation protection and
interpolation, EFM demodulator, error correction, digital

equalizer for servo, and servo controller. The CD processor also
incorporates a 1-bit DA converter. In combination with the TA2157F/FG/FN/FNG digital servo head amplifier, the
TC94A58FAG can very simply configure an adjustment-free CD player.
Thus, the IC is suitable for CD systems for automobiles and radio-cassette players.
Features
Single-chip CD processor with on-chip CMOS LCD driver and 4-bit microcontroller
Operating supply voltage:
CD in operation: VDD = 3.0 to 3.6 V (3.3 V typ.)
