DESCRIPTION
The M27C516 is a 512 Kbit EPROM offered in the
OTP range (one time programmable). It is ideally
suited for microprocessor systems requiring large
data or program storage and is organized as
32,768 words of 16 bits.
The M27C516 is offered in a PLCC44 and TSOP40
(10 x 14mm) packages.

Notes: 1. Except for the rating ”Operating Temperature Range”, stresses above those listed in the Table ”Absolute Maximum Ratings”
may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other
conditions above those indicated in the Operating sections of this specification is not i mplied. Exposure to Absolute Maximum
Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other
relevant quality documents.
2. Minimum DC voltage on Input or Output is –0.5V with possible undershoot to –2.0V for a period less than 20ns. Maximum DC
voltage on Output is VCC +0.5V with possible overshoot to VCC +2V for a period less than 20ns.
3. Depends on range.
