Renesas M5M5V108DFP-70H#ST

Overview

M5M5V108DFP-70H#ST from Renesas Technology Corp. is a 131,072-word × 8-bit (1 Mbit) CMOS static RAM with 70 ns access time, 2.7–3.6 V supply, 5 mA active current, and 24 µA standby current at 1 MHz-designed for battery-backed memory units in embedded controllers and portable instrumentation.

For engineers reviewing the M5M5V108DFP-70H#ST datasheet, M5M5V108DFP-70H#ST pinout, M5M5V108DFP-70H#ST application, or M5M5V108DFP-70H#ST equivalent, key selection criteria include TTL-compatible I/O, dual chip select (S1/S2) for memory expansion, three-state outputs with OR-tie capability, and +2 V data retention during power-down.

Technical Context

This SRAM uses triple-polysilicon/double-metal CMOS process with TFT load cells to achieve high density and low power. It supports three operational modes-read, write, and non-selection-controlled by S1, S2, W, and OE inputs, enabling flexible memory mapping and power management.

The device implements two distinct power-down paths: S1-controlled (S1 ≥ V_CC−0.2 V, S2 ≤ 0.2 V) and S2-controlled (S2 ≤ 0.2 V), both guaranteeing data retention down to +2.0 V supply and limiting ICC(PD) to ≤20 µA at 85°C.

FAQ

What is the maximum operating temperature range for the M5M5V108DFP-70H#ST?

The M5M5V108DFP-70H#ST is rated for operation from –40°C to +85°C ambient temperature. This industrial-grade thermal specification ensures reliable performance in harsh environments such as factory automation panels, outdoor telemetry units, and under-hood automotive modules. All DC and AC electrical characteristics-including 70 ns access time and 24 µA standby current-are guaranteed across this full range.

Does the M5M5V108DFP-70H#ST support true 3.3 V operation without level shifting?

Yes, the M5M5V108DFP-70H#ST operates natively from 2.7 V to 3.6 V and features TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.6 V) and CMOS-compatible outputs. When powered at 3.3 V, it interfaces directly with standard 3.3 V microcontrollers and FPGAs-no external level shifters or resistive dividers are needed for signal integrity or timing compliance.

How does the dual chip select (S1/S2) architecture of the M5M5V108DFP-70H#ST simplify memory expansion?

The M5M5V108DFP-70H#ST uses independent S1 and S2 inputs to implement hierarchical chip selection: S1 enables the device, while S2 determines whether the chip responds to read/write cycles or enters high-impedance standby. This allows up to 16 devices to share a common address/data bus using simple OR-tied S2 lines-eliminating address decoder ICs and reducing PCB layer count in multi-bank memory systems.

Can the M5M5V108DFP-70H#ST retain data during complete power loss?

The M5M5V108DFP-70H#ST does not retain data after full power loss, but it maintains stored contents down to +2.0 V supply voltage. When paired with a backup source (e.g., coin cell or supercapacitor), it provides seamless data hold during brown-outs, controlled shutdowns, or brief AC interruptions-critical for medical devices and industrial controllers requiring deterministic state recovery.

What is the function of the NC pins on the M5M5V108DFP-70H#ST package?

The M5M5V108DFP-70H#ST has two NC (No Connection) pins: Pin 9 and Pin 25. These terminals are not bonded internally and must remain electrically floating in the PCB layout. Neither grounding nor routing signals to these pins is permitted, as doing so may compromise timing margins or cause undefined behavior during S1/S2-controlled power-down sequences.
