Weekly Progress
Today my company are discussion project. I tested ic isd1420. It is ic
for records sound . ic have 28 pin .ic includes devices offered at 8kHz
sampling frequencies. The speech samples are stored directly into on-
chip novolatile memory
the pin REC input is an active low record signal. The dvivce records
whenever REC is low. This signal must remain Low for the duration of the
recording . REC takes precedence over either playback a playback
cycle,the play back immediately ceases and recording begins.
Figure 1 IC ISD1420
Figure 2 Application Example
I can play audio In press PLAYE. When this input signal transitions from HIGH to LOW , a playback
cycle is initiated. curcuit Example from datasheet of ic .
Engineering Analysis
Strong Point
-IC isd1420 Single-Chip Voice Record/Playback Devices
16- and 20-Second Durations
Week Point
-Sound recordings are not good.
Next Week Job
-connection with Microcontrollers.
- I records new Sound.
