RAS and CAS are used to strobe the row address and the column address, respectively. The A428316 has two CAS inputs: LCAS controls I/O0I/O7, and UCAS controls I/O8 - I/O15, UCAS and LCAS function in an identical manner to CAS in that either will generate an internal CAS signal. The CAS function and timing are determined by the first CAS ( UCAS or LCAS ) to transition low and by the last to transition high. Byte Read and Byte Write are controlled by using LCAS and UCAS separately. A Read cycle is performed by holding the W E signal high during RAS / CAS operation. A Write cycle is executed by holding the W E signal low during RAS / CAS operation; the input data is latched by the falling edge of W E or CAS , whichever occurs later. The data inputs and outputs are routed through 16 common I/O pins, with RAS , CAS , W E and OE controlling the in direction. EDO Page Mode operation all 512 columns within a selected row to be randomly accessed at a high data rate. A EDO Page Mode cycle is initiated with a row address latched by RAS followed by a column address latched by CAS . While holding RAS low, CAS can be toggled to strobe changing column addresses, thus achieving shorter cycle times. The A428316 offers an accelerated Fast Page Mode cycle through a feature called Extended Data Out, which keeps the output drivers on during the CAS precharge time (tcp). Since data can be output after CAS goes high, the user is not required to wait for valid data to appear before starting the next access cycle. Data-out will remain valid as long as RAS and OE are low, and W E is high; this is the only characteristic which differentiates Extended Data Out operation from a standard Read or Fast Page Read. A memory cycle is terminated by returning both RAS and CAS high. Memory cell data will retain its correct state by maintaining power and accessing all 512 combinations of the 9-bit row addresses, regardless of sequence, at least once every 8ms through any RAS cycle (Read, Write) or RAS Refresh cycle ( RAS -only, CBR, or Hidden). The CBR Refresh cycle automatically controls the row addresses by invoking the refresh counter and controller. Power-On The initial application of the VCC supply requires a 200 µs wait followed by a minimum of any eight initialization cycles containing a RAS clock. During Power-On, the VCC current is dependent on the input levels of RAS and CAS . It is recommended that RAS and CAS track with VCC or be held at a valid VIH during Power-On to avoid current surges.

ICC1, ICC3, ICC4, and ICC5 depend on cycle rate. 2. ICC1 and ICC4 depend on output loading. Specified values are obtained with the outputs open. 3. An initial pause of 200µs 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. 4. AC Characteristics assume tT = 2ns. All AC parameters are measured with a load equivalent to two TTL loads and 50pF, VIL (min.) ≥ GND and VIH (max.) ≤ VCC. 5. VIH (min.) and VIL (max.) are reference levels for measuring timing of input signals. Transition times are measured between VIH and VIL. 6. 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. 7. 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. 8. Assumes three state test load (5pF and a 500Ω Thevenin equivalent). 9. Either tRCH or tRRH must be satisfied for a read cycle. 10. tOFF (max.) defines the time at which the output achieves the open circuit condition; it is not referenced to output voltage levels. 11. tWCS, tWCH, tRWD, tCWD and tAWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS ≥ 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 entire cycle. If tRWD ≥ tRWD (min.) , tCWD ≥ tCWD (min.) and tAWD ≥ tAWD (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 conditions is satisfied, the condition of the data out at access time is indeterminate. 12. These parameters are referenced to UCAS and LCAS leading edge in early write cycles and to W E leading edge in read-modify-write cycles. 13. Access time is determined by the longer of tAA or tCAC or tCPA. 14. tASC ≥ tCP to achieve tPC (min.) and tCPA (max.) values.

Entering the Self Refresh Mode: The A428316 Self Refresh Mode is entered by using CAS before RAS cycle and holding RAS and CAS signal “low” longer than 100µs. b. Continuing the Self Refresh Mode: The Self Refresh Mode is continued by holding RAS “low” after entering the Self Refresh Mode. It does not depend on CAS being “high” or “low” after entering the Self Refresh Mode continue the Self Refresh Mode. c. Exiting the Self Refresh Mode: The A428316 exits the Self Refresh Mode when the RAS signal is brought “high”.
