Description
The Hitachi HM51W16400 Series, HM51W17400 Series are CMOS dynamic RAMs organized 4,194,304word × 4-bit. They employ the most advanced 0.5 µm CMOS technology for high performance and low
power. The HM51W16400 Series, HM51W17400 Series offer Fast Page Mode as a high speed access
mode. They have package variations of standard 300-mil 26-pin plastic SOJ and standard 300-mil 26-pin
plastic TSOP.

Notes: 1. AC measurements assume tT = 5 ns.
2. An initial pause of 200 µs is required after power up followed by a minimum of eight initialization
cycles (any combination of cycles containing RAS-only refresh or CAS-before-RAS refresh). If
the internal refresh counter is used, a minimum of eight CAS-before-RAS refresh cycles are
required.
3. Operation with 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 .
4. Operation with 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 .
5. Either tOED or tCDD must be satisfied.
6. Either tDZO or tDZC must be satisfied.
7. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Also, transition
times are measured between VIH (min) and VIL (max).
8. Assumes that tRCD ≤ tRCD (max) and tRAD ≤ tRAD (max). If tRCD or tRAD is greater than the maximum
recommended value shown in this table, tRAC exceeds the value shown.
9. Measured with a load circuit equivalent to 1 TTL loads and 100 pF. (V OH = 2.0 V, VOL = 0.8 V)
10. Assumes that tRCD ≥ tRCD (max) and tRCD + tCAC (max) ≥ tRAD + tAA (max).
11. Assumes that tRAD ≥ tRAD (max) and tRCD + tCAC (max) ≤ tRAD + tAA (max).
12. Either tRCH or tRRH must be satisfied for a read cycles.
13. tOFF (max) and tOEZ (max) define the time at which the outputs achieve the open circuit condition
and are not referred to output voltage levels.
14. tWCS , tRWD, tCWD, tAWD and tCPW 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) throughout the entire cycle; if tRWD
≥ tRWD (min), tCWD ≥ tCWD (min), and tAWD ≥ tAWD (min), or tCWD ≥ tCWD (min), tAWD ≥ tAWD (min) and tCPW ≥
tCPW (min), the cycle is a read-modify-write and the data output 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.
15. These parameters are referred to CAS leading edge in early write cycles and to WE leading edge
in delayed write or read-modify-write cycles.
16. tRASP defines RAS pulse width in Fast page mode cycles.
17. Access time is determined by the longest among tAA , tCAC and tCPA.
18. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data
to the device.

HM51W16400 Series, HM51W17400 Series
19. The 16M DRAM offers a 16-bit time saving parallel test mode. Address CA0 and CA1 for the 4M
× 4 are don’t care during test mode. Test mode is set by performing a WE-and-CAS-before-RAS
(WCBR) cycle. In 16-bit parallel test mode, data is written into 4 bits in parallel at each I/O (I/O1
to I/O4) and read out from each I/O.
If 4 bits of each I/O are equal (all 1s or 0s), data output pin is a high state during test mode read
cycle, then the device has passed. If they are not equal, data output pin is a low state, then the
device has failed.
Refresh during test mode operation can be performed by normal read cycles or by WCBR refresh
cycles.
To get out of test mode and enter a normal operation mode, perform either a regular CAS-beforeRAS refresh cycle or RAS-only refresh cycle.
20. In a test mode read cycle, the value of tRAC , tAA, tCAC and tCPA is delayed by 2 ns to 5 ns for the
specified value. These parameters should be specified in test mode cycles by adding the above
value to the specified value in this data sheet.
21. Please do not use tRASS timing, 10 µs ≤ tRASS ≤ 100 µs. During this period, the device is in
transition state from normal operation mode to self refresh mode. If tRASS > 100 µs, then RAS
precharge time should use tRPS instead of tRP.
22. If you use distributed CBR refresh mode with 15.6 µs interval in normal read/write cycle, CBR
refresh should be executed with in 15.6 µs immediately after exiting from and before entering into
self refresh mode.
23. If you use RAS only refresh or CBR burst refresh mode in normal read/write cycle, 4096 or 2048
cycles (4096 cycles: HM51W16400 Series, 2048 cycles: HM51W 17400 Series) of distributed
CBR refresh with 15.6 µs interval should be executed with in 64 or 32 ms (64 ms: HM51W16400
Series, 32 ms: HM51W17400 Series) immediately after exiting from and before entering into the
self refresh mode.
24. Repetitive self refresh mode without refreshing all memory is not allowed. Once you exit from
self fresh mode, all memory cells need to be refreshed before re-entering the self refresh mode
again.
25. XXX: H or L (H: VIH (min) ≤ VIN ≤ VIH (max), L: VIL (min) ≤ VIN ≤ VIL (max))
///////: Invalid Dout
When the address, clock and input pins are not described on timing waveforms, their pins must
be applied VIH or VIL.
