Product details
Overview
CY7C107D-10VXI from Cypress Semiconductor is a 1-Mbit (1,048,576 × 1) high-speed CMOS static RAM with 10 ns access time, TTL-compatible I/O, and automatic CE-controlled power-down. It operates at 5 V ±0.5 V over –40 °C to +85 °C, draws 80 mA active current and 3 mA CMOS standby current (ISB2), and supports 2.0 V data retention-used in legacy industrial controllers requiring fast, low-power, pin-compatible SRAM replacement.
For engineers reviewing the CY7C107D-10VXI datasheet, CY7C107D-10VXI pinout, CY7C107D-10VXI application, or CY7C107D-10VXI equivalent, key selection criteria include its 28-pin 400-mil SOJ package, TTL-level input compatibility (VIH = 2.2 V min), 10 ns tAA timing, automatic CE-driven power-down, and suitability for systems where CMOS input thresholds are not required.
Technical Context
This SRAM implements a synchronous, address-decoded 1M×1 array with dual-stage decoding (row/column), on-chip sense amplifiers, and tri-state output drivers controlled by CE and WE. Its TTL-compatible inputs accept VIH ≥ 2.2 V and VIL ≤ 0.8 V, enabling direct interfacing with legacy 5 V microcontrollers and FPGAs without level-shifting.
The device enters low-power ISB2 mode (<3 mA) when CE is deasserted (HIGH) under CMOS input conditions (VIN > VCC–0.3 V or <0.3 V), and transitions DOUT to high-impedance within 5 ns of CE HIGH. Data retention is guaranteed down to 2.0 V VCC with no clock or address activity required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 1,048,576 × 1-bit - supports bit-slice expansion in wide-data bus systems |
| Access Time (tAA) | 10 ns - enables operation with 100 MHz read cycles in tightly timed control loops |
| Supply Voltage | 5.0 V ±0.5 V - compatible with standard 5 V logic rails and legacy power domains |

| CMOS Standby Current (ISB2) | 3 mA - enables low-power sleep modes without external power gating circuitry |
| Data Retention Voltage | 2.0 V - allows battery-backed hold during brown-out or controlled shutdown sequences |
| Input Compatibility | TTL-level only (VIH ≥ 2.2 V) - excludes direct use with pure CMOS 5 V processors requiring ≥3.5 V VIH |

| WE | Write Enable | Active LOW write strobe; combined with CE LOW to initiate write cycle; disables DOUT during write |
| VCC / GND | Power / Ground | 5 V supply pair; decoupling required per SOJ thermal resistance (θJA = 58.76 °C/W) |
Key Features
| Feature | Design Value |
|---|---|
| Pin- and function-compatible with CY7C107B/CY7C1007B | Drop-in replacement for field-upgraded legacy systems without PCB redesign |
| Automatic CE-controlled power-down | Reduces ICC from 80 mA to 3 mA instantly upon deselection-no software or external logic needed |
| TTL-compatible I/O | Eliminates level shifters when interfacing with 8051, Z80, or older FPGA families |
| 2.0 V data retention | Preserves memory contents during brown-out or backup-battery operation without refresh |
| High-impedance output control | DOUT enters Hi-Z within 5 ns of CE HIGH or WE LOW-prevents bus contention in multi-SRAM systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C107B-10VXI | Same 1M×1 organization and 10 ns speed, but lacks Pb-free packaging and updated ISB2 spec (10 mA vs. 3 mA) | Not suitable for new RoHS-compliant designs; higher standby draw increases thermal load in dense modules | Select only for exact form-fit replacement in legacy assemblies with existing CY7C107B BOMs |
| AS6C1008-10TIN | 1M×1, 10 ns, 5 V, but CMOS-input only (VIH ≥ 3.5 V); ISB2 = 1 µA (lower), no TTL compatibility | Requires level-shifting for legacy 5 V TTL buses; incompatible with direct 8051/Z80 interfaces | Prefer for new designs with CMOS-native controllers where ultra-low standby (<1 µA) is critical |
Compared with CY7C107B-10VXI, the CY7C107D-10VXI delivers 65% lower standby current and Pb-free compliance; versus AS6C1008-10TIN, it trades 3 mA ISB2 for guaranteed TTL interoperability-making it optimal for retrofitting aging industrial hardware without signal conditioning.

FAQ
Is CY7C107D-10VXI compatible with 3.3 V systems?
No. The device requires 5.0 V ±0.5 V supply and is specified only for 5 V operation. Its TTL-compatible inputs (VIH ≥ 2.2 V) and outputs (VOH ≥ 2.4 V) are not guaranteed to interface reliably with 3.3 V logic families without level translation. Operating outside 4.5–5.5 V violates Absolute Maximum Ratings and may cause data corruption or accelerated wear.
What is the maximum clock frequency supported for continuous read cycles?
The device supports up to 100 MHz read cycles, derived from its 10 ns tRC (read cycle time). This assumes proper AC loading (30 pF), 3 ns input rise/fall times, and 1.5 V timing reference levels. Sustained operation at this rate requires adequate PCB layout, decoupling, and thermal management given its 80 mA ICC and θJA of 58.76 °C/W.
Can CY7C107D-10VXI be used with modern microcontrollers like STM32 or RP2040?
Only with level-shifting circuitry. Its TTL input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V) do not meet the CMOS VIH requirement (≥3.5 V at 5 V VDD) of most modern MCUs. Direct connection risks read failures or excessive input leakage. Use a dedicated level translator such as TXB0108 or discrete resistor-divider networks validated per AN6081.
Does the device require an external clock or refresh signal?
No. As a static RAM, CY7C107D-10VXI is fully asynchronous and requires no clock, refresh, or periodic access to retain data. Data remains valid as long as VCC stays ≥2.0 V and CE remains HIGH in retention mode. All timing is controlled solely by CE, WE, and address transitions per the truth table and switching waveforms in the datasheet.
