QV301m

Features:

General description:

The QV301m modules provide a simple method of adding voice and sound to your system. They

comprise a controller based on a Microchip PIC processor, an ISD4003-04 ChipCorder

recording chip with four minutes capacity at 4kHz bandwidth, and an audio amplifier of various

power ratings. A line level output is also available. The modules are controlled with a simple two-

wire, 9600B, RS232 connection (the return path is optional) or through the parallel connection.

The QV301m modules can operate in parallel mode stand-alone or with a microcontroller, or in

serial mode, in which case the function is identical to that of the QV305 except that the Baud rate

is fixed at 9600 and hard RESET line is not available.

Parallel mode:

The QV301 controller provides a simplified interface to the ISD4000 family ChipCorder

recording chips. The QV301m is optimized for simple processor-less systems where the primary

function is the playing back of pre-recorded messages. Nonetheless, it is possible to control the

301 with a microprocessor, and to record messages using the built-in sequentially addressed

record function.

By taking advantage of the ChipCorder’s

separate messages without explicit reference to physical addresses. Four phrase selection

modes are provided and are selected via resistor programming of the mode select pins M0 and

M1. As these pins are read continuously, the addressing mode can be changed between

operations.
