The AS4C14400 is fabricated with advanced CMOS technology and designed with innovative design techniques resulting in high speed, extremely low power and wide operating margins at component and system levels. The AS4C14400 features a high speed page mode operation in which high speed read, write and read-write are performed on any of the 1024 x 4 bits defined by the column address. The asynchronous column address uses an extremely short row address capture time to ease the system level timing constraints associated with multiplexed addressing. Output is tri-stated by a column address strobe (CAS) which acts as an output enable independent of RAS. Very fast CAS to output access time eases system design. Refresh on the 1024 address combinations of A0 to A9 during a 16 ms period is accomplished by performing any of the following: * RAS-only refresh cycles * Hidden refresh cycles * CAS-before-RAS refresh cycles * Normal read or write cycles The AS4C14400 is available in JEDEC standard 20/26-pin plastic SOJ and 20/26-pin plastic TSOP packages. System level features include single power supply of 5.0 0.5V tolerance and direct interface with TTL logic families.

ICC1 and ICC4 depend on output loading. Specified values are obtained with the output open. An initial pause of 200 s is required after power-up followed by any 8 RAS cycles before proper device operation is achieved. In the case of an internal refresh counter, a minimum of 8 CAS-before-RAS initialization cycles instead of 8 RAS cycles are required. 8 initialization cycles are required after extended periods of bias without clocks (greater than 16 ms). AC Characteristics assume tT = 5 ns. All AC parameters are measured with a load equivalent to two TTL loads and 100 pF, V IL (min) GND and VIH (max) VCC. See AC test conditions for more information. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Transition times are measured between V IH and VIL . Operation within the t RCD (max) limit ensures that tRAC (max) can be met. tRCD (max) is specified as a reference point only. If tRCD is greater than the specified tRCD (max) limit, then access time is controlled exclusively by tCAC. Operation within the t RAD (max) limit ensures that tRAC (max) can be met. tRAD (max) is specified as a reference point only. If tRAD is greater than the specified tRAD (max) limit, then access time is controlled exclusively by tAA. Assumes three state test load (5 pF and a 380 Thevenin equivalent). Either tRCH or tRRH must be satisfied for a read cycle. tOFF (max) defines the time at which the output achieves the open circuit condition; it is not referenced to output voltage levels. tWCS, tWCH , tRWD, tCWD and tAWD are not restrictive operating parameters. They are included in the datasheet as electrical characteristics only. If t WCS tWCS (min) and tWCH tWCH (min), the cycle is an early write cycle and data out pins will remain open circuit, high impedance, throughout the cycle. If tRWD tRWD (min), tCWD tCWD (min) and tAWD tAWD (min), the cycle is a read-write cycle and the data out will contain data read from the selected cell. If neither of the above conditions is satisfied, the condition of the data out at access time is indeterminate. These parameters are referenced to CAS leading edge in early write cycles and to WE leading edge in read-write cycles. Access time is determined by the longest of tCAA or tCAC or tCAP. tASC tCP to achieve t PC (min) and tCAP (max) values. These parameters are sampled and not 100% tested. 4 5 6 7 8 9 10 11 12 13 14 15 AC test conditions - Access times are measured with output reference levels of VOH = 2V and VOL = 0.8 V - Input rise and
