ISD5008 Series ChipCorder

Like other ChipCorder products, the ISD5008 integrates the sampling Clock anti-aliasing and smoothing Filters and the multi-level storage array on a single- chip. For enhanced voice features, the ISD5008 eliminates external circuitry by also integrating Automatic gain control (AGC), a power Amplifier speaker driver, Volume Control summing Amplifiers Analog Switches and a car kit Interface Input level adjustable Amplifiers are also included, providing a flexible Interface for multiple applications. Duration/sample rate selection is accomplished via software, allowing customers to optimize quality and duration for various features within the same end product. The ISD5008 device is designed for use in a microprocessor- or microcontroller-based system. Address, control, and duration selection are accomplished through a Serial Peripheral Interface (SPI) or Microwire Serial Interface to minimize pin count. Recordings are stored in on-chip nonvolatile memory cells, providing zero-power message storage. This unique, single-chip solution is made possible through ISDs patented multilevel storage technology. Voice and Audio signals are stored directly into solid-state memory in their natural, uncompressed form, providing superior quality voice and music reproduction. By Winbond Electronics Corp America
