CY14B101L 1 Mbit 128K x 8 nvSRAM Functional Description • 25 ns, 35 ns, and 45 ns Access Times The Cypress CY14B101L is a fast static RAM with a nonvolatile • Pin compatible with STK14CA8 element in each memory cell. The embedded nonvolatile elements incorporate QuantumTrap technology producing the • Hands off Automatic STORE on Power Down with only a small world’s most reliable nonvolatile memory. The SRAM provides Capacitor s • STORE to QuantumTrap Nonvolatile Elements is initiated by software, hardware, or AutoStore on Power Down ign • RECALL to SRAM initiated by Software or Power Up s • Unlimited READ, WRITE, and RECALL Cycles e • 200,000 STORE Cycles to QuantumTrap D • 20 year Data Retention at 55°C • Single 3V +20%, Operation ew • Commercial and Industrial Temperature N • 32-pin 300 mil SOIC and 48-pin 300 mil SSOP packages r • RoHS Compliance unlimited read and write cycles, while independent, nonvolatile data resides in the highly reliable QuantumTrap cell. Data transfers from the SRAM to the nonvolatile elements the STORE operation takes place automatically at power down. On power up, data is restored to the SRAM the RECALL operation from the nonvolatile memory. Both the STORE and RECALL operations are also available under software control. fo Logic Block Diagram ded A5 n A7 e A8 m A12 A 13 A 14 m A15 o A16 ROW DECODER QuantumTrap 1024 x 1024 STORE STATIC RAM ARRAY 1024 X 1024 RECALL VCAP POWER CONTROL STORE/ RECALL CONTROL SOFTWARE DETECT - A15 A0 ec DQ0 R DQ1 tDQ3 oDQ4 NDQ5 COLUMN IO COLUMN DEC A0 A1 A2 A3 A4 A10 A11 INPUT BUFFERS CE WE • San Jose, CA 95134-1709 • 408-943-2600 [+] Feedback CY14B101L Contents Features 1 Ordering Information 15 s These parts are not recommended for new designs. 15 De Package Diagrams 17 Noise Considerations 5 w Low Average Active Power 5 e Preventing Store 6 N Best Practices 6 r Maximum Ratings 8 Not Recommended fo Operating Range 8 Sales, Solutions, and Legal Information 20 Worldwide Sales and Design Support......................... 20 Products 20 Page 2 of 20 [+] Feedback CY14B101L Pinouts Figure Pin Diagram - 32-Pin SOIC and 48-Pin SSOP VCAP 32 VCC VCAP 1 A16 2 31 A15 30 HSB A14 3 A12 4 A7 5 46 HSB 45 WE 29 WE 28 A13 A6 6 A5 7 s A4 8 n A3 9 ig A2 10 s A1 11 e A0 12 D DQ0 13 DQ1 14 w DQ2 15 e VSS 16 27 A8 26 A9 25 A11 24 OE 23 A10 22 CE 21 DQ7 20 DQ6 19 DQ5 18 DQ4 17 DQ3 NC 10 NC 11 NC 12 NC 14 NC 15 DQ0 16 DQ1 21 DQ2 22 NC 23 NC 24 Top View not to scale 38 NC 35 NC 34 NC r N Table Pin Definitions fo Pin Name d e DQ0-DQ7 d WE en CE m OE m VSS o VCC c HSB t Re VCAP No NC I/O Type Input Address Inputs.
