PSD8XXF Family
Preliminary Information

1.0
Introduction
(Cont.)
Please refer to the revision block at the end of this
document for updated information.
The PSD8XXF family includes a JTAG serial programming interface to allow in-system-
programming of the entire device. This feature reduces development time, simplifies the
manufacturing flow, and dramatically lowers the cost of field upgrades. Using Waferscale’s
special Fast-JTAG programming, a design can be programmed into the PSD8XXF in as
little as seven seconds.
The innovative Flash PSD8XXF family solves key problems faced by designers when
managing discrete Flash memory devices, such as:
First-time programming
Complex address decoding
Simultaneous read and write to Flash.
The PSD8XXF’s serial JTAG interface allows in-system-programming and eliminates the
need for a boot EPROM or an external programmer. To simplify Flash updates, the
devices perform program execution out of a Flash Boot block while the main Flash memory
is being updated. This solution avoids the complicated overhead circuitry and
software necessary to implement in-system Flash memory updates.
PSDsoft — Waferscale’s software development tool — now has the ability to generate
ANSI-C compliant code for use with your target MCU. The code generated allows you to
manipulate the non-volatile memory (NVM) within the PSD. Code examples are also
provided for:
Flash ISP via the UART of the host MCU
Memory paging to execute code across several PSD memory pages
Loading, reading, and manipulation of PSD Micro
Cells by the MCU
The PSD8XXF is available in 52-pin PLCC and PQFP package, and a 64-pin plastic Thin
Quad Flatpack (TQFP) package.
A simple interface to 8-bit microcontrollers that use either multiplexed or
non-multiplexed busses. The bus interface logic uses the control signals generated by
the microcontroller automatically when the address is decoded and a read or write is
performed. A partial list of the MCU families supported include:
Intel 8031, 80196, 80186, 80C251, and 80386EX
Motorola 68HC11, 68HC16, 68HC12, and 683XX
Philips 8031 and 8051XA
Zilog Z80 and Z8
Internal 1 or 2 Mbit Flash memory. This is the main Flash memory. It is divided into
eight equal-sized blocks that can be accessed with user-specified addresses.
Internal secondary 256 Kbit Flash boot memory. It is divided into four equal-sized
blocks that can be accessed with user-specified addresses. This secondary memory
brings the ability to execute code and update the main Flash concurrently.
Optional 16 or 64 Kbit SRAM. The SRAM’s contents can be protected from a
power failure by connecting an external battery.
