MB84VD2228XEA

The MB84VD2228XEA is a kind of stacked MCP (multi-chip package) FLASH MEMORY & SRAM CMOS.

The features of MB84VD2228XEA can be summarized as (1)power supply voltage of 2.7 V to 3.3 V; (2)high performance, 90 ns maximum access time (Flash), 70 ns maximum access time (SRAM); (3)operating temperature 25°C to +85°C; (4)package 71-ball BGA.

The absolute maximum ratings of MB84VD2228XEA are (1)storage temperature Tstg: 55 +125 °C; (2)ambient temperature with power applied TA: 25 +85 °C; (3)voltage with respect to ground all pins except A 9 , OE, RESET, WP/ACC (Note 1) V IN , VOUT 0.3V , V CC f +0.3 VCCs +0.4 V; (4)VCCf/VCCs supply (note 1) VCCf, VCC s: 0.3 to +4.0 V; (5)A 9 and OE (Note2) VIN: 0.3 to +13.0 V; (6)RESET (Note 2) VIN: 0.5 to +13.0 V; (7)WP/ACC (Note 3) VIN: 0.5 to +10.5 V( 1. Minimum DC voltage on input or I/O pins is 0.3 V. During voltage transitions, input or I/O pins may undershoot V SS to 2.0 V for periods of up to 20 ns. Maximum DC voltage on input or I/O pins is V CC f +0.3 V or V CC s+0.4 V. During voltage transitions, input or I/O pins may overshoot to V CC f+2.0 V or V CC s+2.0 V for periods of up to 20 ns. 2. Minimum DC input voltage on A 9 and OE pin is 0.3 V. Minimum DC input voltage on RESET pin is 0.5 V. During voltage transitions, A 9 , OE, and RESET pins may undershoot V SS to 2.0 V for periods of up to 20 ns. Voltage difference between input and supply voltage (VIN-V CC f or V CC s) does not exceed 9.0 V. Maximum DC input voltage on A 9 , OE, and RESET pins is +13.0 V which may overshoot to +14.0 V for periods of up to 20 ns. 3. Minimum DC input voltage on WP/ACC pin is 0.5 V. During voltage transitions, WP/ACC pin may undershoot Vss to 2.0 V for periods of up to 20 ns. Maximum DC input voltage on WP/ACC pin is +10.5 V which may overshoot to +12.0 V for periods of up to 20 ns, when V CC f is applied.).
