DESCRIPTION
The TOSI4402AP/AJ/ASJ/AZ is the new generation dynamic RAM organized 1,048,576 words by 4 bits. The TC514402AP/AJ/ASJ/AZ utilizes TOSHIBA’s CMOS Silicon gate process technology as well as advanced circuit techniques to provide wide operating margins, both internally and to the system user. Multiplexed address inputs permit the TC514402AP/AJ/ASJ/AZ to be packaged in a standard 20 pin plastic DIP, 26/20 pin plastic SOJ (300/350mil) and 20 pin plastic ZIP. The package size provides high system bit’ densities and is compatible with widely available automated testing and insertion equipment. System oriented features include single power supply of 5V+10% tolerance, direct interfacing capability with high performace logic families such as Schottky TTL.

NOTES: 1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. 2, All voltages are referenced to Vss. 3. Icc1, Icca, Icc4, Icce depend on cycle rate. 4. Icc1, Icc4 depend on output loading. Specified values are obtained with the output open. 5. Column address can be changed once or less while RAS= Vi. 6. An initial pause of 200ps is required after power-up followed by 8 RAS only refresh cycles before proper device operation is achieved. In case of using internal refresh counter, a minimum of 8 CS before RAS refresh cycles instead of 8 RAS refresh cycles are required. 7. AC measurements assume tr=5ns. 8. Vin (min.) and Vii (max.) are reference levels for measuring timing of input signals. 9, Measured with a load equivalent to 2 TTL loads and 100pF. 10. torr (max.) and togz(max.) define the time at which the output achieves the open circuit condition and are not referenced to output voltage levels. 11, Either tpcH or trrH must be satisfied for a read cycle. 12. These parameters are referenced to CS leading edge in early write cycles and to WRITE leading edge in Read-Modify-Write cycles. 13. twos, twp, tcwp and tawp are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If twcs=twcs(min.), the cycle is an early write cycle and the data out pin will remain open circuit (high impedance) through the entire cycle; If trwp= trwp (min.), tcwp2 town (min.) and tawp2=tawp (min.) the cycle is a Read-Modify-Write cycle and the data out will contain data read from the selected cell: If neither of the above sets of conditions is satisfied, the condition of the data out(at access time) is indeterminate. 14, Operation within the trcp (max.) limit insures that trac (max.)can be met. + trop (max.)is specified as a reference point only: If trop is greater than the specified trcp (max.) limit, then access time is controlled by tcac. 15. Operation within the trap (max.) limit insures that trac (max.)can be met. trap (max.) is specified as a reference point only: If trap is greater than the specified trap (max.) limit, then access time is controlled by taa. * 16. Operation within the thwap (max.) limit insures that taLw (max.) can be met. tLwap (max.) is specified as a reference point only: If trap is greater than the specified tuwap (max.) limit, then access time is controlled by taa. 17. tan is the condition to latch column address ewhen RAS has rised up.
