UNI/O® EEPROM
Using UNI/O EEPROM can free up MCU pins for new features.
Microchip’s new UNI/O Serial EEPROM uses only ONE connection to the
host microcontroller. This compares to two or three pins for I2C, and three
to six pins for Microwire or SPI buses. This new, proprietary bus offers
advanced features like a status register and write-protection on demand,
along with all I/O and memory array and command functions through a
single pin.

Serial SRAM
Do you need a simple, inexpensive way to add RAM to
your application? Microchip offers external RAM where
you need it.
Microchip’s new serial SRAM family provides a way to easily and
inexpensively add external RAM to almost any application. These serial
devices use less power and fewer I/O connections than traditional parallel
SRAM. And, they allow designers to use a smaller microcontroller rather than
moving to a larger microcontroller just to get more on-board RAM.

Wafer-Level Burn-In
Microchip’s best-in-class field performance is the combined result of world class
manufacturing, wafer level burn-in and wafer probe quality screens.
Microchip’s Triple Test Flow is currently the most robust testing procedure for serial EEPROM devices in the
industry. It tests each cell of each die three times and also performs extensive endurance and data retention tests
to ensure quality and reliability.
Infant mortality of Microchip serial EEPROMs is among the lowest in the industry due to this extensive testing,
excellent fabrication and highly reliable memory cell design.
Microchip’s Triple Test and
Wafer-level Burn-in Procedure
Traditional Burn-in
(Old Technology)
General purpose non-specific testing procedure
for random logic cells
■ Non-specific and untargeted testing
mechanism – Increases failure rates.
■ Expensive, time consuming and inefficient.
■ Introduces defect modes like bent leads
and EOS that sometimes go undetected.
Moving beyond traditional burn-in to wafer level burn-in with the Triple
Test Flow specifically targeted for memory cells has helped create the
industry’s most reliable memory products.
■ Extensive Testing – Every cell in every die is tested three times,
including specific endurance and data retention tests to ensure
highest quality.
■ HVST, LVHF and TVPP tests target specific defects.
■ Maverick, SBY and GBN target overall failure patterns and trends.
■ Insight into failure modes along with flexible test flow ensures
continues improvement.
Triple Test Flow
Microchip tests every cell in wafer form twice, then performs a final test after assembly.

Wafer Probe Quality Screens
Microchip performs additional in-house testing during wafer
probe to ensure quality and eliminate any devices that are
outside the normal distribution or might possibly fail in the
future.
High Voltage Stress Test (HVST)
HVST targets weak devices with oxide defects in RAM and logic
circuits by stressing the oxides at higher than normal voltages.
Time at Vpp (TVPP)
TVPP targets oxide defects in EEPROM cells, charge pumps
and other high-voltage circuits. Programming voltages (VPP) are
applied to the memory array for an extended period of time in
order to highlight any weak devices.
Low Voltage High Frequency (LVHF)
LVHF targets signal paths that are partially blocked and therefore
more resistive than normal. LVHF eliminates these devices by
requiring them to operate faster than specified and at voltages
lower than specified.

Resources to Get You Started Quickly
Reduce development time and cost with our development tools.
Competitive market conditions force businesses to examine every aspect of their product life cycle to maximize
productivity and minimize expense. Easy-to-learn, low-cost common development tools are one way to reduce risk
and get to market quicker.
MPLAB® Starter Kit for Serial Memory Products
UNI/O® Bus Parasitic Power Demo Board
(DV243003)
(AC243004)
Reduce time to market and
create a rock-solid design using
the MPLAB Starter Kit for Serial
Memory Products. It includes
everything necessary to quickly
develop a robust and reliable
Serial EEPROM design, and greatly reduces the time
required for system integration and hardware/software
fine-tuning.
■ 3.3V and 5.0V on-board voltage selection
■ Supports Microchip UNI/O bus, I²C, SPI and
Microwire Serial EEPROMs
■ 1.8V to 5.5V external voltage support
■ Includes free copy of MPLAB IDE
■ USB interconnect
The UNI/O Bus Parasitic Power
Demo Board is designed to
illustrate how a standard
half-wave rectifier and
capacitor circuit can be used
to parasitically extract power
for a UNI/O device from the
SCIO signal as described in application note, AN1213
“Powering a UNI/O® Bus Device Through SCIO”. This
reduces the number of connections necessary for
adding a UNI/O device to your application down to two:
SCIO and VSS.
Total Endurance™ Software
Total Endurance Software provides a comprehensive
model that helps estimate the endurance and reliability
of Microchip Serial EEPROM devices. By providing
operating conditions based on your application, all
design trade-offs affecting reliability can be accurately
estimated both graphically and numerically in PPM,
FIT and MTBF modes, saving time and ensuring a truly
robust design.
