Functional description
The AS4C1M16F5 is a high performance 16-megabit CMOS Dynamic Random Access Memory (DRAM) organized as 1,048,576 words x 16 bits. The AS4C1M16F5 is fabricated using advanced CMOS technology and innovative design techniques resulting in high speed, extremely low power and wide operating margins at component and system levels. The Alliance 16Mb DRAM family is optimized for use as main memory in personal and portable PCs, workstations, and multimedia and router switch applications. The AS4C1M16F5 features high speed page mode operation where read and write operations within a single row (or page) can be executed at very high speed (15 ns from XCAS)by toggling column addresses within that row. Row and column addresses are alternately latched into input buffers using the falling edge of RAS and xCAS inputs respectively. Also, RAS is used to make the column address latch transparent, enabling application of column addresses prior to xCAS assertion. The AS4C1M16F5 provides dual UCAS and LCAS for independent byte control of read and write access. Refresh on the 1024 address combinations of A0 to A9 must be performed every 16 ms using:
* RAS-only refresh: RAS is asserted while xCAS is held high. Each of the 1024 rows must be strobed. Outputs remain high impedence. * Hidden refresh: xCAS is held low while RAS is toggled. Outputs remain low impedence with previous valid data. * CAS-before-RAS refresh (CBR): At least one xCAS is asserted prior to RAS. Refresh address is generated internally. Outputs are high-impedence (OE and WE are don't care). * Normal read or write cycles refresh the row being accessed.
The AS4C1M16F5 is available in the standard 42-pin plastic SOJ and the 44/50-pin TSOP II packages, respectively. It operates with a single power supply of 5V 0.5V. The device provides TTL compatible inputs and outputs.

Notes
1 2 3 ICC1, ICC3, and ICC4 are dependent on frequency. 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 8 ms). AC Characteristics assume tT = 2 ns. All AC parameters are measured with a load equivalent to two TTL loads and 100 pF, VIL (min) GND and VIH (max) VCC. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Transition times are measured between VIH and VIL. Operation within the tRCD (max) limit insures 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 tRAD (max) limit insures 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. tOFF is referenced from rising edge of RAS or CAS, whichever occurs last. tWCS, tWCH, tRWD, tCWD and tAWD are not restrictive operating parameters. They are included in the datasheet as electrical characteristics only. If tWS tWS (min) and tWH tWH (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 tCPA tASC tCP to achieve tPC (min) and tCPA (max) values. These parameters are sampled and not 100% tested. These characteristics apply to AS4C1M16F5 5V devices.
