Introduction
The PSD3XX family is the market's first single-chip solution for microcontroller-based
applications where criteria such as fast time-to-market, small form factor, and low power
consumption are essential. When combined in an 8- or 16-bit system, virtually any
microcontroller (68HC11, 8031/8051, 80186, etc.) and the PSD3XX device work together to
create a very powerful chip-set solution. The low-voltage PSD3XXL versions eliminate
mixing and matching low voltage specifications for various discrete components. They also
provide all the required control and peripheral elements needed in a microcontroller-based
system with no external discrete “glue” logic required.
The PSD3XX family comes complete with simple system software development tools
for interfacing the PSD3XX with a microcontroller. Hosted on an IBM PC platform or
compatible, the easy to use PSDsoft software enables the designer to quickly configure the
device and use it immediately.
PSD3XX
standard versions are ideal for general purpose embedded control applications.
PSD3XXR
(SRAM-less) versions are optimized for designs that either require no
on-chip SRAM or require large off-chip SRAMs for data storage. (SRAM-less versions were
formerly identified by a “C1” suffix to the part number.)
PSD3XXM
mask-programmable versions deliver the lowest cost PSD3XX solution. See the
Masked-PSD Ordering Information chapter in this databook for the mask-programmable
PSD3XXM ordering procedure.
PSD3XXL
low-power versions operate down to 3.0 volts and feature standby current of only
1 μA typical.
Combinations of the above versions are available. See the ordering information section at
the end of this data sheet.

PSD3XX, PSD3XXR, PSD3XXM and PSD3XXRM). References to PSD3XXR include any
SRAM-less product (PSD3XXR, PSD3XXRM, PSD3XXRL and PSD3XXRLM). References
to PSD3XXM include PSD3XXM, PSD3XXRM, PSD3XXLM, and PSD3XXRLM products.
