The SMJ27C010A series are 131072 by 8-bit (1048576-
bit), ultaviolet (UV) light erasable, electrically programmable
read-only memories (EPROMs).
These devices are fabricated using power-saving CMOS
technology for high speed and simple interface with MOS and
bipolar circuits. All inputs (including program data inputs)
can be driven by Series 54 TTL circuits without the use of
external pullup resistors. Each output can drive one Series 54
TTL circuit without external resistors.
The SMJ27C010A EPROM is offered in a ceramic

dual-in-line package (J suffix) designed for insertion in
mounting-hole rows on 15.2mm (600mil) centers.
These EPROMs operate from a single 5V supply (in the
read mode), and therefore, are ideal for use in
microprocessor-based systems. One other 13V supply is
needed for programming. All programming signals are TTL
level. These devices are programmable using the SNAP! Pulse
programming algorithm. The SNAP! Pulse programming
algorithm uses a V_PP of 13V and a V_CC of 6.5V for a nominal
programming time of thirteen seconds. For programming
outside the system, existing EPROM programmers can be
used. Locations can be programmed singly, in blocks, or at
random.
