WS57C291C-55TMB

WS57C191C/291C HIGH SPEED 2K x 8 CMOS PROM/RPROM KEY FEATURES • Ultra-Fast Access Time — t ACC = 25 ns — t CS = 12 ns • Pin Compatible with Am27S191/291 and N82S191 Bipolar PROMs • Immune to Latch-UP — Up to 200 mA • Low Power Consumption • Fast Programming • Available in 300 Mil DIP and PLDCC • ESD Protection Exceeds 2000V 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 VCC and ground is recommended. Inadequate decoupling may result in access time degradation or other transient performance failures. 2-10 WS57C191C/291C NORMALIZED SUPPLY CURRENT vs. SUPPLY VOLTAGE 1.60 40.0 35.0 1.40 30.0 NORMALIZED I CC DELTA Taa (ns) 1.20 25.0 20.0 15.0 10.0 5.0 0.60 4.0 4.5 5.0 5.5 6.0 SUPPLY VOLTAGE ( V ) 0.0 TYPICAL ACCESS TIME CHANGE vs. OUTPUT LOADING 1.00 0.80 0.0 200 400 600 800 1000 CAPACITANCE ( pF ) NORMALIZED Taa vs. AMBIENT TEMPERATURE 1.6 1.2 NORMALIZED SUPPLY CURRENT vs. AMBIENT TEMPERATURE 1.4 1.1 NORMALIZED Taa 1.2 NORMALIZED I CC 1.0 1.0 0.9 0.8 0.6 -55 -35 -15 5 25 45 65 85 105 125 AMBIENT TEMPERATURE (°C ) 0.8 -55 -35 -15 5 25 45 65 85 105 125 AMBIENT TEMPERATURE (°C) 2-11 WS57C191C/291C PROGRAMMING INFORMATION DC CHARACTERISTICS (TA = 25 ± 5°C, VCC = 6.25 V ± 0.25 V, VPP = 12.75 ± 0.25 V) SYMBOLS ILI IPP ICC VOL VOH PARAMETER Input Leakage Current (VIN = VCC or Gnd) VPP Supply Current During Programming Pulse VCC Supply Current Output Low Voltage During Verify (IOL = 16 mA) Output High Voltage During Verify (IOH = –4 mA) 2.4 MIN –10 MAX 10 60 25 0.45 UNITS µA mA mA V V NOTES: 8.
