Product details
Overview
CY62138FV30LL-45ZAXA from Cypress Semiconductor is a 2-Mbit (256 K × 8) CMOS static RAM with 45 ns access time, 2.2–3.6 V supply voltage, and ultra-low standby current (1 µA typical). It operates across –40 °C to +85 °C and supports automatic power-down when deselected via dual chip enables (CE1/CE2), targeting battery-powered portable electronics requiring fast, low-power memory.
For engineers reviewing the CY62138FV30LL-45ZAXA datasheet, CY62138FV30LL-45ZAXA pinout, CY62138FV30LL-45ZAXA application, or CY62138FV30LL-45ZAXA equivalent, key selection criteria include its dual CE architecture for hierarchical memory mapping, MoBL® low-power design validated at 1 MHz active current (1.6 mA), and compatibility with legacy CY62138CV series in multiple packages.
Technical Context
This SRAM implements a synchronous, non-volatile-retentive volatile memory array with complementary metal oxide semiconductor (CMOS) process technology optimized for speed-power trade-off. Its dual chip enable (CE1 LOW + CE2 HIGH) logic enables selective bank activation in multi-chip systems, while automatic power-down triggers on CE1 HIGH or CE2 LOW transitions.
The device uses eight bidirectional I/O pins (I/O0–I/O7) with high-impedance control during deselect, OE HIGH, or write cycles. Addressing is performed over 18 address lines (A0–A17), supporting full 256K-word decoding without external address latching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 256 K × 8 bits = 2 Mbit; supports byte-wide data bus interface without width expansion logic |
| Access time | 45 ns max; enables direct interfacing with microcontrollers running at ≤22 MHz system clock |
| VCC range | 2.20 V to 3.60 V; compatible with single-supply Li-ion battery systems (3.0–3.6 V) and regulated 2.5 V rails |
| Standby current | 1 µA typical / 5 µA max; reduces quiescent drain in sleep modes of handheld devices |
| Active current | 1.6 mA typical at 1 MHz; enables sustained burst reads/writes with sub-2 mW dynamic power at 3.3 V |
| Operating temperature | –40 °C to +85 °C; qualified for industrial and automotive-A environments without derating |
| Data retention voltage | 1.5 V min; allows memory state hold during brown-out or backup-battery operation |
Pinout & Package
Package: 36-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA), 0.5 mm pitch, 6 mm × 8 mm footprint. Pin-compatible with TSOP I/II, SOIC, and STSOP variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| I/O0–I/O7 | Bidirectional data I/O | 8-bit parallel data path; tri-stated automatically on CE/OE/WE control transitions |
| CE1, CE2 | Dual chip enable inputs | AND-logic enable: CE1 LOW AND CE2 HIGH activates device; either HIGH/LOW disables and powers down |
| OE | Output enable | Controls output buffer only; does not affect power state-device remains active if CE1/CE2 enabled |
| WE | Write enable | Active-LOW signal initiating write cycle; overlaps with CE assertion to define internal write window |
| VCC, VSS | Power and ground | Single 2.2–3.6 V supply; no separate I/O or core voltage rails required |
| NC | No-connect | Two unconnected balls (A17, A16); must be left floating or grounded per PCB layout guidelines |

FAQ
What is the function of CE1 and CE2 in CY62138FV30LL-45ZAXA?
CE1 and CE2 form a dual-input chip enable with AND logic: the device activates only when CE1 is LOW and CE2 is HIGH. Either CE1 HIGH or CE2 LOW forces automatic power-down and places all I/Os in high-impedance state. This enables hierarchical memory banking and eliminates need for external decode logic in multi-SRAM systems.
Does CY62138FV30LL-45ZAXA support data retention below normal operating voltage?
Yes-it retains stored data down to VCC = 1.5 V, with ICCDR ≤ 4 µA at that voltage. This allows continued memory state preservation during brown-out conditions or when backed by a supercapacitor or coin cell, provided CE1/CE2 remain in power-down state.
Can CY62138FV30LL-45ZAXA operate reliably at 2.2 V supply?
Yes-its full specification, including 45 ns access time and 1 µA standby current, is guaranteed across 2.2 V to 3.6 V. At 2.2 V, VIH is 1.8 V min and VIL is 0.6 V max, ensuring robust noise margin with 1.8 V logic interfaces.
Is the 36-ball VFBGA package of CY62138FV30LL-45ZAXA RoHS-compliant?
Yes-the "ZAXA" suffix denotes a Pb-free, RoHS-compliant 36-ball VFBGA package with NiPdAu surface finish, qualified to JEDEC J-STD-020 moisture sensitivity level 3 and rated for reflow peak temperatures up to 260 °C.
