AT27C516
1. Description
The AT27C516 is a low-power, high-performance 524,288-bit one-time programmable
read-only memory (OTP EPROM) organized 32K by 16 bits. It requires only one 5V
power supply in normal read mode operation. Any word can be accessed in less than
45 ns, eliminating the need for speed reducing WAIT states. The by-16 organization
make this part ideal for high-performance 16- and 32-bit microprocessor systems.
In read mode, the AT27C516 typically consumes 15 mA. Standby mode supply cur-
rent is typically less than 10 µA.
The AT27C516 is available in industry-standard JEDEC-approved one-time program-
mable (OTP) plastic PLCC and VSOP packages. The device features two-line control
(CE, OE) to eliminate bus contention in high-speed systems.
With 32K word storage capability, the AT27C516 allows firmware to be stored reliably
and to be accessed by the system without the delays of mass storage media.
Atmel’s AT27C516 have additional features to ensure high quality and efficient pro-
duction use. The Rapid Programming Algorithm reduces the time required to program
the part and guarantees reliable programming. Programming time is typically only
50 µs/word. The Integrated Product Identification Code electronically identifies the
device and manufacturer. This feature is used by industry standard programming
equipment to select the proper programming algorithms and voltages.
