MOTOROLA SEMICONDUCTOR TECHNICAL DATA Product Preview 2M x 2 Bit Fast Static Random Access Memory with ECL I/O The MCM101525 is a 4,194,304 bit static random access memory organized as 2,097,152 words of 2 bits. This device features complementary outputs. This circuit is fabricated using high performance silicon–gate BiCMOS technology. Asynchronous design eliminates the need for external clocks or timing strobes. The MCM101525 is available in a 400 mil, 36 lead TAB. • Fast Access Times: 12, 15 ns • Equal Address and Chip Select Access Time • Power Operation: – 195 mA Maximum, Active AC BLOCK DIAGRAM A17 A16 VEE A15 VCC A14 A13 A12 ROW DECODER MEMORY MATRIX 1024 ROWS x 4096 COLUMNS A11 A10 A9 A8 D0 D1 Q0 Q0 Q1 Q1 S W INPUT DATA CONTROL COLUMN I/O COLUMN DECODER A20 A19 A18 A7 A6 A5 A4 A3 A2 A1 A0 Q0 Q0 Q1 Q1 Order this document by MCM101525/D MCM101525 TB PACKAGE 400 MIL TAB CASE 984A–01 PIN ASSIGNMENT A10 1 A11 2 A12 3 A13 4 A14 5 S6 D0 7 Q0 8 VCC 9 VEE 10 Q0 11 VEE 12 W 13 A0 14 A15 15 A16 16 A17 17 A18 18 36 A1 35 A2 34 A3 33 A8 32 A19 31 NC 30 A20 29 Q1 28 VEE 27 VCC 26 Q1 25 D1 24 NC 23 A9 22 A4 21 A5 20 A6 19 A7 PIN NAMES A0 – A20 . . . . . . . . . . . . .

A write occurs during the overlap of S low and W low. 2. Product sensitivites to noise require proper grounding and decoupling of power supplies during read and write cycles. 3. All write cycle timings are referenced from the last valid address to the first transitioning address. 4. This parameter is sampled and not 100% tested.
