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 current is typically less than 10 µA.
The AT27C516 is available in industry-standard JEDEC-approved one-time programmable (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 production 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.

3. System Considerations
Switching between active and standby conditions via the Chip Enable pin may produce transient voltage excursions. Unless accommodated by the system design, these transients may
exceed datasheet limits, resulting in device non-conformance. At a minimum, a 0.1 µF high
frequency, low inherent inductance, ceramic capacitor should be utilized for each device. This
capacitor should be connected between the VCC and Ground terminals of the device, as close
to the device as possible. Additionally, to stabilize the supply voltage level on printed circuit
boards with large EPROM arrays, a 4.7 µF bulk electrolytic capacitor should be utilized, again
connected between the VCC and Ground terminals. This capacitor should be positioned as
close as possible to the point where the power supply is connected to the array.

18. Rapid Programming Algorithm
A 50 µs PGM pulse width is used to program. The address is set to the first location. VCC is
raised to 6.5V and VPP is raised to 13.0V. Each address is first programmed with one 50 µs
PGM pulse without verification. Then a verification/reprogramming loop is executed for each
address. In the event a word fails to pass verification, up to 10 successive 50 µs pulses are
applied with a verification after each pulse. If the word fails to verify after 10 pulses have been
applied, the part is considered failed. After the word verifies properly, the next address is
selected until all have been checked. VPP is then lowered to 5.0V and VCC to 5.0V. All words
are read again and compared with the original data to determine if the device passes or fails.
