GENERAL DESCRIPTION
The EN27C010 is a low-power 1-Megabit, 5V-only one-time-programmable (OTP) read-only
memory (EPROM). Organized into 128K words with 8 bits per word, it features QuikRiteTM single-
address location programming, typically at 20µs per byte. Any byte can be accessed in less than
45ns, eliminating the need for WAIT states in high-performance microprocessor systems. The
EN27C010 has separate Output Enable ( OE ) and Chip Enable ( CE ) controls which eliminate
bus contention issues.

FUNCTIONAL DESCRIPTION
THE QUIKRITETM PROGRAMMING OF THE EN27C010
When the EN27C010 is delivered, the chip has all 1M bits in the “ONE”, or
HIGH state. “ZEROs” are loaded into the EN27C010 through the procedure of programming.
The programming mode is entered when 12.75 ± 0.25V is applied to the VPP pin, OE is at VIH,
and CE and PGM are at VIL. For programming, the data to be programmed is applied with 8
bits in parallel to the data pins.
The QUIKRITETM programming flowchart in Figure 5 shows Eon’s interactive programming
algorithm. The interactive algorithm reduces programming time by using 20 µs to 100 µs
programming pulses and giving each address only as many pulses as is necessary in order to
reliably program the data. After each pulse is applied to a given address, the data in that
address is verified. If the data is not verified, additional pulses are given until it is verified or
until the maximum number of pulses is reached. This process is repeated while sequencing
through each address of the EN27C010. This part of the programming algorithm is done at
VCC = 6.25V to assure that each EPROM bit is programmed to a sufficiently high threshold
voltage. This ensures that all bits have sufficient margin. After the final address is completed,
the entire EPROM memory is read at VCC = VPP = 5.25 ± 0.25V to verify the entire memory.
