MOTOROLA Order this document by MCM6208C/D SEMICONDUCTOR TECHNICAL DATA MCM6208C 64K x 4 Fast Static RAM The MCM6208C is fabricated using Motorola's high-performance silicon-gate CMOS technology. Static design eliminates the need for external clocks or timing strobes, while CMOS circuitry reduces power consumption and provides for greater reliability. This device meets JEDEC standards for functionality and pinout, and is available in plastic dual-in-line and plastic small-outline J-leaded packages. * * * * * * P PACKAGE 300 MIL PLASTIC CASE 724A-01 Single 5 V 10% Power Supply Fully Static -- No Clock or Timing Strobes Necessary Fast Access Times: 12, 15, 20, 25, and 35 ns Equal Address and Chip Enable Access Times Low Power Operation: 135 -165 mA Maximum AC Fully TTL Compatible -- Three-State Output J PACKAGE 300 MIL SOJ CASE 810A-02 PIN ASSIGNMENT BLOCK DIAGRAM A0 1 24 VCC A1 2 23 A15 A2 3 22 A14 A3 4 21 A13 A4 5 20 A12 A5 6 19 A11 A12 A6 7 18 A10 A13 A7 8 17 DQ0 A14 A8 9 16 DQ1 A9 10 15 DQ2 E 11 14 DQ3 VSS 12 13 W A1 A2 VCC A3 VSS A4 A6 MEMORY ARRAY 256 ROWS x 64 x 4 COLUMNS ROW DECODER COLUMN I/O DQ0 DQ1 DQ2 INPUT DATA CONTROL COLUMN DECODER PIN NAMES DQ3 A0 E A5 A7 A8 A9 A10 A11 A15 A0 - A15 . . . . . . . . . . . . .

This CMOS 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. Storage Temperature -- Plastic Tstg - 55 to + 125 C NOTE: Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. Functional operation should be restricted to RECOMMENDED OPERATING CONDITIONS. Exposure to higher than recommended voltages for extended periods of time could affect device reliability.

W is high for read cycle. 2. All timings are referenced from the last valid address to the first transitioning address. 3. Addresses valid prior to or coincident with E going low. 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 500 mV from steady-state voltage with load of Figure 1B. 6. This parameter is sampled and not 100% tested. 7. Device is continuously selected (E1 VIL). TIMING LIMITS AC TEST LOADS +5V RL = 50 OUTPUT 480 OUTPUT Z0 = 50 255 5 pF VL = 1.5 V Figure 1A MOTOROLA FAST SRAM Figure 1B The table of timing values shows either a minimum or a maximum limit for each parameter. 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.
