DESCRIPTION
aP89021/010 high performance Voice OTP is fabricated with Standard CMOS process with embedded
512K/256K bits EPROM. It can store up to 21/10 sec voice message with 4-bit ADPCM compression
at 6KHz sampling rate. 8-bit PCM is also available as user selectable option. Two trigger modes,
simple Key trigger mode and Parallel CPU trigger mode facilitate different user interface. User
selectable triggering and output signal options provide maximum flexibility to various applications.
Built-in resistor controlled oscillator, 8-bit current mode D/A output and PWM direct speaker driving
output minimize the number of external components. PC controlled programmer and developing
software are available.

Dimension: 1.9cm x 0.8cm x 0.7cm
