INTEGRATED CIRCUITS INC.- APR9301 APR9301 RE-RECORDING VOICE IC Single-Chip Voice Recording & Playback Device for Single 20 to 30 Second Message Features : Single-chip, high quality voice recording & Playback solution - No external ICs required - Minimum external components Non-volatile Flash memory technology - No battery backup required - 100K record cycles (typical) - 100-year message retention (typical) Single message of 20 to 30 seconds, with external resistor selection Chip enable pin for simple message expansion User-friendly, easy-to-use operation - Programming & development systems not required - Level-activated recording & edge-activated playback switches Low power consumption - Operating current: 25mA (typical, no load) - Standby current: 1uA (typical, no load) Automatic power-down feature for longer battery life Single 5V power supply General Description : The APR9301 device offers true single-chip solid-state storage capability and requires no software or microcont-roller support. It provides high-quality recording and playback with a single 20- to 30-second message. It is ideal for portable voice recorders, toys, and many other consumer and industrial applications. APLUS’s proprietary analog/multi-level storage technology is implemented in advanced Flash non-volatile memory cells,each of which can typically store more than 256 voltage levels. The APR9301 device stores and reproduces voice signals in their natural forms, eliminating distortion that is often introduced by encoding and compression. The device combines a small size with low power consumption,non-volatility, and ease-of-use for a cost effective solution to voice recording and playback http://www.aplusinc.com.tw Page 1 / 10 VER2.3 INTEGRATED CIRCUITS INC.- APR9301 PS : The APR9301 DIP & SOP is not [ PIN to PIN ] Functional Block Diagram : Figure 2 shows the functional block diagram for the APR9301 device.
