description

The SMJ27C128 series is a set of 131072-bit, ultraviolet-light erasable, electrically programmable read-only memories. These devices are fabricated using HVCMOS technology for high speed and simple interfacing 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. The data outputs are three-state for connecting multiple devices to a common bus. The SMJ27C128 is pin-compatible with 28-pin 128K ROMs and EPROMs. They are offered in a 600-mil dual-in-line ceramic package (J suffix) rated for operation from -55°C to 125°C.

Since these EPROMs operate from a single 5-V supply (in the read mode), they are ideal for use in microprocessor-based systems. One other (12.5 V) supply is needed for programming, but all programming signals are TTL-level. These devices are programmable by either Fast or SNAP! Pulse programming algorithms. The Fast programming algorithm uses a V_PP of 12.5 V and a V_CC of 6 V for a nominal programming time of two minutes. The SNAP! Pulse programming algorithm uses a V_PP of 13.0 V and a V_CC of 6.5 V for a nominal programming time of two seconds. For programming outside the system, existing EPROM programmers can be used. Locations can be programmed singly, in blocks, or at random.
