MOTOROLA Order this document by MCM6709AR/D SEMICONDUCTOR TECHNICAL DATA MCM6709AR 64K x 4 Bit Static RAM The MCM6709AR is a 262,144 bit static random access memory organized as 65,536 words of 4 bits, fabricated using high–performance silicon–gate BiCMOS technology. Static design eliminates the need for external clocks or timing strobes. Output enable (G) is a special control feature that provides increased system flexibility and eliminates bus contention problems. The MCM6709AR meets JEDEC standards and is available in a revolutionary pinout 300 mil, 28 lead plastic surface–mount SOJ package. • • • • • • Single 5 V ± 10% Power Supply Fully Static — No Clock or Timing Strobes Necessary All Inputs and Outputs are TTL Compatible Center Power and I/O Pins for Reduced Noise Three State Outputs Fast Access Times: MCM6709AR–6 = 6 ns MCM6709AR–7 = 7 ns J PACKAGE 300 MIL SOJ CASE 810B–03 PIN ASSIGNMENT A0 1 28 A15 A1 2 27 A14 A2 3 26 A13 A3 4 25 A12 E 5 24 G DQ0 6 23 DQ3 VCC 7 22 VSS A VSS 8 21 VCC A DQ1 9 20 DQ2 A W 10 19 A11 BLOCK DIAGRAM A ROW DECODER A A MEMORY MATRIX 512 ROWS x 128 x 4 COLUMNS •• • A A4 11 18 A10 A5 12 17 A9 A6 13 16 A8 A7 14 15 NC A A PIN NAMES DQ0 •• • •• • COLUMN I/O •• • INPUT DATA CONTROL COLUMN DECODER DQ3 A E W G A A A A A A A0 – A15 . . . . . . . . . . . .

Functional operation should be restricted to RECOMMENDED OPERATING CONDITIONS. Exposure to higher than recommended voltages for extended periods of time could affect device reliability. Storage Temperature — Plastic This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high–impedance circuit. This BiCMOS memory circuit has been designed to meet the dc and ac specifications shown in the tables, after thermal equilibrium has been established. The circuit is in a test socket or mounted on a printed circuit board and transverse air flow of at least 500 linear feet per minute is maintained.

W is high for read cycle. 2. Product sensitivities to noise require proper grounding and decoupling of power supplies as well as minimization or elimination of bus contention conditions during read and write cycles. 3. .All read cycle timings are referenced from the last valid address to the first transitioning address. 4. At any given voltage and temperature, tEHQZ max is less than tELQX min, and tGHQZ max is less than tGLQX min, both for a given device and from device to device. 5. Transition is measured 200 mV from steady–state voltage with load of Figure 1B. 6. This parameter is sampled and not 100% tested.

Input requirements are specified from the external system point of view. Thus, address setup time is shown as a minimum since the system must supply at least that much time (even though most devices do not require it). On the other hand, responses from the memory are specified from the device point of view. Thus, the access time is shown as a maximum since the device never provides data later than that time.
