ISD1700 SERIES

5 PIN DESCRIPTION

Refer to Design Guide for details before performing any design or PCB layout.

PIN NAME

V_CCD

FUNCTIONS

Digital Power Supply: Power supply for digital circuitry.

LED: An LED output.

LED

RESET: When active, the device enters into a known state.

RESET

MISO

Master In Slave Out: Data is shifted out on the falling edge of SCLK.

When the SPI is inactive ( SS = high), it’s tri-state.

MOSI

SCLK

Master Out Slave In: Data input of the SPI interface when ISD1700 is a

slave. Data is latched into the device on the rising edge of SCLK.

Serial Clock: Clock of the SPI interface.

Slave Select: Selects as a slave device and enables the SPI interface.

V_SSA

Analog Ground: Ground path for analog circuitry.

AnaIn

MIC+

MIC-

AnaIn: Auxiliary analog input to the device for recording or feed-through.

MIC+: Non-inverting input of the differential microphone signal.

MIC-: Inverting input of the differential microphone signal.

V_SSP2

SP-

Ground: Ground path for negative PWM speaker drive.

SP-: The negative Class D PWM speaker output.

V_CCP

Power Supply for PWM Speaker Driver: Power for PWM speaker drive.

SP+: The positive Class D PWM speaker output.

SP+

V_SSP1

AUD/AUX

Ground: Ground path for positive PWM speaker drive.

Auxiliary Output: Either an AUD (current) or AUX (voltage) output.

Automatic Gain Control (AGC): The AGC adjusts the gain of the

microphone preamplifier circuitry.

AGC

Volume: This control has 8 levels of volume adjustment.

VOL

R_OSC

Oscillator Resistor: A resistor determines the sample frequency of the

device, which sets the duration.

V_CCA

Analog Power Supply. Power supply for analog circuitry.

Feed-through: Enable the feed-through path for AnaIn signal to the

outputs.

Playback: Plays the recorded message individually, or plays messages

sequential in a looping mode.

PLAY

Record: When active, starts recording message.

REC

Erase: When active, can erase individual message or do global erase.

Forward: Advances to the next message from the current location.

An open drain output. Can review ready or interrupt status.

ERASE

FWD

RDY INT

V_SSD

Digital Ground: Ground path for digital circuitry
