ISD1820

ISD1820 Voice Record Module is base on ISD1820, which a multiple-message record/playback device. It can offers true single-chip voice recording, no-volatile storage, and playback capability for 8 to 20 seconds. The sample is 3.2k and the total 20s for the Recorder. This module use is very easy which you could direct control by push button on board or by Microcontroller such as Arduino, STM32, ChipKit etc. Frome these, you can easy control record , playback and repeat and so on. Feature         Push-button interface, playback can be edge or level activated Automatic power-dwon mode On-chip 8Ω speaker driver Signal 3V Power Supply Can be controlled both manually or by MCU Sample rate and duration changable by replacing a single resistor Record up to 20 seconds of audio Dimensions: 37 x 54 mm If you want change record duration, an external resistor is necessary to select the record duration and sampling frequency, which can range from 8 – 20 seconds (4-12kHz sampling frequency). The Voice Record Module of our provide default connect 100k resistor through P2 by short cap. So the default record duration is 10s. Free Datasheet http://www.nDatasheet.com 1. PLAYE – Playback, Edge-activated:When a HIGH-going transition is detected on continues until an End-of-Message (EOM) marker is encountered or the end of the memory space is reached. 2. REC – The REC input is an active-HIGH record signal.The device records whenever REC is HIGH. This pin must remain HIGH for the durati...
