1 General Description Features est Series is a series of 3 to 340 seconds single chip high quality voice synthesizer IC which contains one 4-bit Input port (provided for est005 and above); three 4-bit I/O ports; and a tiny controller. est Series provides strong features and uses improved algorithm to achieve pure speech. By programming through the tiny controller, user s applications, such as section combination, trigger mode, control outputs, keyboard matrix and other logic functions, can be easily implemented.

4 Application Circuit Important notes for the following application circuits: 1. For noisy power supply application, suppress noise by adding ceramic capacitor between and ground near the IC s pad. The recommend capacitor value is 0.1µF. 2. For heavy loading application, it is recommended that an electrolytic capacitor is added between and ground. The recommended capacitor value for button cell applications is 10µF. 3. The recommended value for button cell internal impedance is 750Ω or less. 4. The use of spring direct trigger is not recommended. If you must use such trigger, you need to add a ceramic capacitor between trigger pin and ground to debounce the spring noise. The recommend capacitor value is ~ 0.01 µf. est003 Application Circuit for 6-Key 104 VSSC P21 P20 P33 P32 This specification is subject to change without further notice. ( V1.0) Page 4 of 7
