AN231E04 Datasheet – Dynamically Reconfigurable dpASP
The AN231E04 device is an “Analog Signal Processor”; ideally
suited to signal conditioning, filtering, gain, rectification, summing,
subtracting, multiplying, etc.
The device also accommodates nonlinear functions such as
sensor response linearization and arbitrary waveform synthesis.
The AN231E04 device consists of a 2x2 matrix of fully
Configurable Analog Blocks (CABs), surrounded by
programmable interconnect resources and analog input/output
cells with active elements. On chip clock generator block controls
multiple non-overlapping clock domains generated from an
external stable clock source. Internal band-gap reference
generator is used to create temperature compensated reference
voltage levels. The inclusion of an 8x256 bit look-up table
enables waveform synthesis and several non-linear functions.
Configuration data is stored in an on-chip SRAM configuration
memory. An SPI like interface is provided for simple serial load of
configuration data from a microprocessor or DSP. This memory is
shadowed allowing a different circuit configuration to be loaded
as a background task without disrupting the current circuit
The AN231E04 device features seven configurable input/output
structures each can be used as input or output, 4 of the 7 have
integrated differential amplifiers. There is also a single chopper
stabilized amplifier that can be used by 3 of the 7 output cells.
Circuit design is enabled using Anadigmdesigner2 software, a
high level block diagram based circuitry entry tool. Circuit
functions are represented as CAMs (Configurable Analog
Modules) these are configurable block which map onto portions
of CABs. The software and a development board facilite instant
prototyping of any circuit captured in the tool.

With dynamic reconfigurability, the functionality of the
AN231E04 can be reconfigured in-system by the designer or
on-the-fly by a microprocessor. A single AN231E04 can thus
be programmed to implement multiple analog functions
and/or to adapt on-the-fly to your circuit requirements.
