TMS4C2972

The TMS4C2972 is a field memory that is upwardly and pin-to-pin compatible with the TMS4C2970 and TMS4C2971, expect for the consequences of the block size change. The features of the TMS4C2972 are: (1)single 5-V power supply; (2)upwardly and pin-to-pin compatible with TMS4C2970 and TMS4C2971; (3)2-port memory with FIFO operation; (4)optional random-block access function enabled during reset operation, two modes for writes access: D0-or IE-controlled; (5)fully static; (6)write-mask function by input enable; (7)cascade connection capability; (8)high-speed read/write operation.

The following is about the absolute maximum ratings of TMS4C2972: (1)supply voltage range: 0V to 7.0V; (2)voltage range on any input pin: -1.0 to 7.0V; (3)voltage range on any nonlnput pin: -1.0 to 7.0V; (4)voltage difference current: -0.7 to 0.7V; (5)short-circuit output current, IOS: 50mA; (6)power dissipation: 1.0W; (7)operating free-air temperature range, TA: 0 to 70; (8)storage temperature range: -55 to 150.

The electrical characteristics of the TMS4C2972 are: (1)high-level output voltage: 2.4V min at IOH=-5mA; (2)low-level output voltage: 0.4V max at IOL=4.2mA; (3)input current: ±10A max at VI=0V to 6.5V, VDD=5V, all orthers=0V to VDD; (4)output current: ±10A max at VO=0V to VDD, VDD=5V, RE, OE low; (5)average operating current: 50mA at minimum write/read cycle, output open; (6)average standby current: 15mA max at after one RSTW/RSTR cycle, WE, RE, OE low.
