HMD8M32F4E
32Mbyte(8Mx32) EDO Mode 4K Ref. 100Pin SMM, 5V Design
Part No. HMD8M32F4E
GENERAL DESCRIPTION
The HMD8M32F4E is a 8M x 32bit dynamic RAM high density memory module. The module consists of four CMOS
4M x 16 bit DRAMs in 50-pin TSOP packages mounted on a 100-pin, double-sided, FR-4-printed circuit board. A 0.1uF
or 0.22uF decoupling capacitor is mounted on the printed circuit board for each DRAM components.
The module is a single In-line memory module with edge connections and is intended for mounting in to 100-pin edge
connector sockets. All module components may be powered from a single 5V DC power supply and all inputs and
outputs are TTL-compatible.

NOTES
1. An initial pause of 200µs is required after power-up followed by any 8 /RAS-only or /CAS-before-/RAS refresh
cycles before proper device operation is achieved.
2. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Transition times are measured
between VIH(min) and VIL(max) and are assumed to be 5ns for all inputs.
3. Measured with a load equivalent to 1TTL loads and 100pF
4. 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 t CAC.
5. Assumes that tRCD ≥ tRCD(max)
6. tAR, tWCR, tDHR are referenced to tRAD(max)
7. This parameter defines the time at which the output achieves the open circuit condition and is not referenced to
VOH or VOL.
8. tWCS, tRWD, tCWD and tAWD are non restrictive operating parameter.
They are included in the data sheet as electrical characteristic only. If t WCS ≥ tWCS(min) the cycle is an early write
cycle and the data out pin will remain high impedance for the duration of the cycle.
9. Either tRCH or tRRH must be satisfied for a read cycle.
10. These parameters are referenced to the /CAS leading edge in early write cycles and to the /W leading edge in readwrite cycles.
11. 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 by t AA.
