GENERAL DESCRIPTION
The SMJ27C512 is a set of 65536 by 8-bit (524,288-bit), ultraviolet (UV) light
erasable, electrically programmable read-only memories. 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 data outputs are 3-state for connecting multiple
devices to a common bus. The SMJ27C512 is pin-compatible with existing 28-pin
512K ROMs and EPROMs.
Because this EPROM operates from a single 5V supply (in the read mode), it is
ideal for use in microprocessor-based systems. One other supply (13V) is
needed for programming. All programming signals are TTL level. This device is
programmable by the SNAP! Pulse programming algorithm. The SNAP! Pulse
programming algorithm uses a VPP of 13V and a VCC of 6.5V for a nominal
programming time of seven seconds. For programming outside the system,
existing EPROM programmers can be used. Locations may be programmed singly, in
blocks, or at random.
