RENESAS HM62V16256CLTT-5

To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

conditions and are not referred to output voltage levels.
2. This parameter is sampled and not 100% tested.
3. At any given temperature and voltage condition, t HZ max is less than tLZ min both for a given device
and from device to device.
4. A write occures during the overlap of a low CS1, a high CS2, a low WE and a low LB or a low UB.
A write begins at the latest transition among CS1 going low, CS2 going high, WE going low and LB
going low or UB going low. A write ends at the earliest transition among CS1 going high, CS2
going low, WE going high and LB going high or UB going high. tWP is measured from the beginning
of write to the end of write.
5. t CW is measured from the later of CS1 going low or CS2 going high to the end of write.
6. t AS is measured from the address valid to the beginning of write.
7. t WR is measured from the earliest of CS1 or WE going high or CS2 going low to the end of write
cycle.

3. CS2 controls address buffer, WE buffer, CS1 buffer, OE buffer, LB, UB buffer and Din buffer. If
CS2 controls data retention mode, Vin levels (address, WE, OE, CS1, LB, UB, I/O) can be in the
high impedance state. If CS1 controls data retention mode, CS2 must be CS2 ≥ V CC – 0.2 V or 0 V
≤ CS2 ≤ 0.2 V. The other input levels (address, WE, OE, LB, UB, I/O) can be in the high
