PSD7XX Family
13-2
J
The PSD7XX provides all the supervisory functions required for a microcontroller
based system. The supervisory features include:
– System power supply monitoring with configurable trip points.
– User programmable WatchDog Timer, controlled by PPLD product terms.
– Reset generation based on input from:
1. Voltage comparator with programmable internal or external trip point.
2. Push button or system reset input.
3. WatchDog Timer time out.
– Automatic battery-backup of internal SRAM
– Write protect of internal SRAM and external battery back up device.
– Reset input debounce filter.
– Programmable reset pulse width generator.
J
Power Management Unit reduces the device standby current to 25 μA typical.
J
Twenty seven individually configurable I/O Port pins. The Ports may be used as MCU
I/Os, PLD I/Os, latched MCU address outputs or special function I/Os. Sixteen I/O port
pins can be configured as open drain outputs.
J
Internal EPROM in densities of 256 Kbit, 512 Kbit and 1 Mbit, configurable in eight
or sixteen-bit widths. The EPROM is divided into eight equal-size blocks, accessible
by user-specified addresses. The access time includes address latching and PLD
decoding. The EPROM includes a low power option.
J
Internal 4 Kbit SRAM can be configured in eight or sixteen-bit data widths. The
SRAM retains data if power is lost by automatically switching to standby power.
J
A page register expands the microcontroller address space by a factor of sixteen.
J
A security bit prevents copying the PSD7XX configuration and PLD logic as well as
the EPROM contents on device programmers.
J
The programmable Power Management Unit (PMU) supports two separate, low-power
modes allowing operations with as little as 25 μA (at 5V V
CC
). The device can
automatically detect a lack of microcontroller activity and put the PSD into power down
mode.
J
The devices are available in EPROM versions. The ceramic package is ideal for
prototyping and low-volume production, and in OTP versions for high-volume, low-cost
applications.
J
Package choices include 52 pin plastic (J) and ceramic (L) chip carriers.
J
PSD7XX family development is supported by the WSI PC based PSDsoft
design
system. The software is MS-Windows
and Windows 95 compatible. The suite
includes PSDabel
(ABEL
), to specify the PLD logic, and an efficient fitter. The tool
also includes the PSDsilosIII simulator from SIMUCAD
. The MagicPro
III programmer
is an engineering development tool and can program any PSD device.
