QP27C256 & QP27C256L
QP27C256 – 256 Kilobit (32K x 8) CMOS EPROM
June 18, 2009
General Description
The QP27C256 is a 32Kx8 (256-Kbit), UV erasable programmable read-only memory. It operates from a single +5 V
supply, has a static standby mode, and features fast single address location programming. The QP27C256 meets the
same specification requirements and utilizes the same programming methodology as the AMD 27C256 that it replaces.
Products are available in windowed and non-windowed (OTP) ceramic hermetic packages.
Data is typically accessed in less than 55 ns, allowing high-performance microprocessors to operate without any WAIT
states. The device offers separate Output Enable ( OE ) and Chip Enable ( CE ) pins, eliminating bus contention in a
multiple bus system.
Typical power consumption is only 80 mW in active mode, and 100 μW in standby mode.
All signals are TTL levels, including programming signals. Bit locations may be programmed singly, in blocks, or at
random. The device is programmed identically to the AMD27C256 device that it replaces, using the same programming
algorithm (100 us pulses).
The QP27C256 features:
- Same programming algorithm as the AMD27C256, allowing it to be programmed using the same equipment,
data and algorithm. When programming this device select AMD as the manufacturer and 27C256 as the device
type.
- Speed options as fast as 55ns
- JEDEC Pinout
- Single +5V power supply
- CMOS and TTL input/output compatibility
- Two line control functions
- Programming time typically 4 seconds.
The device/family is constructed using an advanced UV CMOS wafer fabrication process.

QP27C256 & QP27C256L
\5 – Minimum DC Input Voltage on input or I/O pins –0.5V. During voltage transitions, the input may overshoot VSS to –
2.0V for periods of up to 20ns. Maximum DC voltage on input and I/O pins is VCC+0.5V. During transitions, input
and I/O pins may overshoot to VCC +2.0V for periods up to 20ns.
\6 – Minimum DC Input Voltage on A9 is –0.5V. During voltage transitions, A9 and VPP may overshoot VSS to –2.0V for
periods of up to 20ns. A9 and VPP must not exceed +13.5V at any time.
\7 – Do not exceed 125ºC TC or TJ for plastic package devices.
\8 – Maximum PD, Maximum TJ Are Not to Be Exceeded.
\9 – During transitions, the inputs may undershoot to –2.0 V dc for periods less than 20 ns.
\10 – VPP may be connected directly to VCC except during programming.
\11 – Qualification Only.
\12 – If not tested, shall be guaranteed to the limits specified.
