ISD1600B SERIES 5. PIN DESCRIPTION PIN NAME SOIC / PDIP FUNCTIONS PIN NO. VSSD 1 Digital Ground: VSSD is the ground for digital circuits. It is important to have a separate path for each ground back to the system ground terminal to minimize noise. REC 2 Record: The device starts recording whenever REC transits from High to Low and stays at Low. Recording stops when the signal returns to High. This pin has an internal pull-up resistor [1] and an internal debounce on falling edge.
ISD1600B SERIES PIN NAME SOIC / PDIP FUNCTIONS PIN NO. VCCA 10 VCCP 10 SP+ 11 AGC 12 Analog power supply: It is important to have a separate path for each power back to the power terminal to minimize the noises. Decoupling capacitors to VSSA should be as close to the device as possible. VCCP: Power supply for PWM speaker drivers. It is important to have a separate path for each power back to the power terminal to minimize noise.
ISD1600B SERIES 6. FUNCTIONAL DESCRIPTION 6.1. DETAILED DESCRIPTION 6.1.1 Audio Quality Winbond’s patented ChipCorder® MLS technology provides natural high quality record and playback solution on a single chip. The input audio signals are stored directly into the nonvolatile memory and are reproduced in its natural form without any compression artifacts caused by the digital speech solutions. A complete sample is stored in a single cell, minimizing the memory needed to store a single message. 6.1.
ISD1600B SERIES at the end of the message. During a record cycle, the device powers down immediately after REC is released to High. 6.2. FUNCTIONAL DESCRIPTION EXAMPLE The following example operating sequences demonstrate the functionality of the ISD1600B series. 6.2.1. Record a Message The device starts recording from the beginning of the memory when REC transits from High to Low and stays at Low. A record cycle is completed when REC is pulled to High or entire memory is filled up.
