WS57C51C HIGH SPEED 16K x 8 CMOS PROM/RPROM KEY FEATURES • Very Fast Access Time • Pin Compatible with Am27S51 — 35 ns and N82HS1281 • Immune to Latch-Up • Low Power Consumption • Fast Programming — Up to 200 mA • ESD Protection Exceeds 2000 V GENERAL DESCRIPTION The WS57C51C is a High Performance 128K 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. A further advantage of the WS57C51C over Bipolar PROM devices is the fact that it utilizes a proven EPROM technology. This enables the entire memory array to be tested for switching characteristics and functionality after assembly. Unlike devices which cannot be erased, every WS5751C in a windowed package is 100% tested with worst case test patterns both before and after assembly. The WS57C51C provides a low power alternative to those designs which are committed to a Bipolar PROM footprint. It is a direct drop-in replacement for a Bipolar PROM of the same architecture (16K x 8). No software, hardware or layout changes need be performed.

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. 2-50 WS57C51C NORMALIZED SUPPLY CURRENT vs. SUPPLY VOLTAGE TYPICAL ACCESS TIME CHANGE vs. OUTPUT LOADING 1.60 40.0 35.0 1.40 DELTA Taa (ns) NORMALIZED I CC 30.0 1.20 1.00 25.0 20.0 15.0 10.0 0.80 5.0 0.60 0.0 4.0 4.5 5.0 5.5 6.0 0.0 200 SUPPLY VOLTAGE ( V ) 400 600 800 1000 CAPACITANCE ( pF ) NORMALIZED Taa vs. AMBIENT TEMPERATURE NORMALIZED SUPPLY CURRENT vs. AMBIENT TEMPERATURE 1.6 1.2 1.4 NORMALIZED I CC NORMALIZED Taa 1.1 1.2 1.0 1.0 0.9 0.8 0.6 0.8 -55 -35 -15 5 25 45 65 85 AMBIENT TEMPERATURE (°C ) 105 125 -55 -35 -15 5 25 45 65 85 105 125 AMBIENT TEMPERATURE (°C) 2-51 WS57C51C PROGRAMMING INFORMATION DC CHARACTERISTICS (TA = 25 ± 5°C, VCC = 6.25 V ± 0.25 V, VPP = 12.75 ± 0.25 V) SYMBOLS NOTE: PARAMETER MIN MAX UNITS –10 10 µA ILI Input Leakage Current (VIN = VCC or Gnd) IPP VPP Supply Current During Programming Pulse 60 mA ICC VCC Supply Current 25 mA VOL Output Low Voltage During Verify (IOL = 16 mA) 0.45 V VOH Output High Voltage During Verify (IOH = –4 mA) 2.4 V 7.
