WS57C191C0/291C HIGH SPEED 2K x 8 CMOS PROM/RPROM KEY FEATURES Pin Compatible with Am27S191/291 and N82S191 Bipolar PROMs Immune to Latch-UP Up to 200 mA ESD Protection Exceeds 2000V Ultra-Fast Access Time tacc = 25ns tes = 12ns Low Power Consumption Fast Programming Available in 300 Mil DIP and PLDCC GENERAL DESCRIPTION The WS57C191C/291C is an extremely High Performance 16K UV Erasable Electrically Re-Programmable Read Only Memory (RPROM). It is manufactured in an advanced CMOS technology which enables it to operate at Bipolar PROM speeds while consuming only 25% of the power required by its Bipolar counterparts. The WS57C191C/291C is also configured in the standard Bipolar PROM pinout which provides an easy upgrade path for systems which are currently using Bipolar PROMs. The WS57C191C is packaged in a conventional 600 mil DIP package as well as a Plastic Leaded Chip Carrier (PLDCC) and a Ceramic Leadless Chip Carrier (CLLCC). The WS57C291C is packaged in a space saving 300 mil DIP package configuration. Both are available in commercial, industrial, and military operating temperature ranges.

Timing measurements are made at 1.5 V for input and output transitions in both directions. NOTE: 6. Provide adequate decoupling capacitance as close as possible to this device to achieve the published A.C. and D.C. parameters. A 0.1 microfarad capacitor in parallel with a 0.01 microfarad capacitor connected between Voc and ground is recommended. Inadequate decoupling may result in access time degradation or other transient performance failures. 2-10WS57C191C/291C NORMALIZED Icc NORMALIZED Taa 1.60 1.40 1.20 1.00 0.80 0.60 1.6 1.4 1.2 1.0 0.8 0.6 NORMALIZED SUPPLY CURRENT vs. SUPPLY VOLTAGE Z | a 4.0 4.5 5.0 5.5 6.0 SUPPLY VOLTAGE (V) NORMALIZED Tag vs. AMBIENT TEMPERATURE 15 5 25 45 65 85 105 125 AMBIENT TEMPERATURE (C) -55 -35 TYPICAL ACCESS TIME CHANGE vs. OUTPUT LOADING 40.0 35.0 30.0 LO @ 25.0 LZ ~ YY S F 20.0 <t A iW 15.0 10.0 7 5.0 Z 0.0 0.0 200 400 600 800 1000 CAPACITANCE (pF) NORMALIZED SUPPLY CURRENT vs. AMBIENT TEMPERATURE 1.2 1.1 - g WN a NI lu 5 1.0 a1. = a 5 pL | = 0.9 0.8 15 5 25 45 65 85 105 125 AMBIENT TEMPERATURE (C) -55 -35 2-11WS57C191C/291C PROGRAMMING INFORMATION DC CHARACTERISTICS (1, = 25+45, Voc = 6.25 V + 0.25 V, Vpp = 12.75 + 0.25 V) SYMBOLS PARAMETER MIN MAX UNITS Input Leakage Current _ Iu (Viv = Veo or Gnd) 10 10 HA Ipp Vpp Supply Current During 60 mA Programming Pulse loc Voc Supply Current 25 mA Output Low Voltage During Verify Vo.
