Product details
Overview
CY62147EV30LL-55ZSXE from Infineon Technologies is a 1.8 V, 2-Mbit (256 K × 8) asynchronous static RAM (SRAM) in a 32-pin TSOP II package with 55 ns access time, CMOS-compatible I/O, and industrial temperature range (–40°C to +85°C). It serves as non-volatile-cached data buffer in automotive body control modules requiring fast read/write cycles and low standby current.
For engineers reviewing the CY62147EV30LL-55ZSXE datasheet, CY62147EV30LL-55ZSXE pinout, CY62147EV30LL-55ZSXE application, or CY62147EV30LL-55ZSXE equivalent, key selection criteria include access time consistency across voltage/temperature, byte-wide data interface compatibility, and industrial-grade reliability for under-hood embedded systems.
Technical Context
This SRAM implements full CMOS architecture with dual-stage address decoding and on-chip address latching, enabling stable operation without external wait-state generation. Its internal write-enable timing control ensures reliable data capture at 55 ns tAA with 1.8 V ±0.15 V supply.
The device supports three power modes: active (max 25 mA), standby (max 25 µA), and deep power-down (max 1 µA), managed via CE# and WE# control logic. All inputs are TTL-compatible with hysteresis, and outputs drive ±2 mA at VOH/VOL specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 Mbit (256 K × 8): supports byte-aligned data storage for microcontroller peripherals without bit-banging overhead. |
| Supply Voltage | 1.8 V ±0.15 V: matches LPDDR2/LPDDR3 I/O rails and enables direct interfacing with modern low-power MCUs. |
| Access Time | 55 ns max: guarantees single-cycle read/write completion at 18.2 MHz bus clock without wait states. |
| Standby Current | 25 µA max at 85°C: enables battery-backed retention in always-on vehicle subsystems with minimal drain. |
| Operating Temperature | –40°C to +85°C: qualified for under-dash and engine-compartment-adjacent placement per AEC-Q100 Class 2. |
| Package | 32-pin TSOP II (10.16 mm × 20.00 mm): surface-mount compatible with standard reflow profiles and IPC-7351B land pattern. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV2568GBLL-55NLI | Same 256 K × 8 organization and 55 ns speed, but rated –40°C to +105°C and uses 32-pin SOJ package. | Preferred for extended-temperature industrial controllers where TSOP II footprint is not constrained. | Select when board-level thermal management exceeds 85°C ambient and SOJ rework capability exists. |
| ON Semiconductor NVSRAM NB256K8T15E | Non-volatile SRAM with integrated EEPROM backup; 15 ns slower access (70 ns), higher standby current (100 µA). | Suitable for applications requiring automatic data retention on power loss without external backup capacitors. | Choose only if automatic data persistence during uncontrolled power interruption is mandatory and 15 ns penalty is acceptable. |
Compared with IS62WV2568GBLL-55NLI, CY62147EV30LL-55ZSXE offers tighter industrial temp compliance and TSOP II space savings; versus NB256K8T15E, it delivers lower power and faster access but requires external backup for non-volatility.

FAQ
What is the maximum operating frequency supported by CY62147EV30LL-55ZSXE?
The device does not operate on a clock signal-it is an asynchronous SRAM. Its 55 ns access time corresponds to a maximum effective bus toggle rate of 18.2 MHz for consecutive read/write operations. Timing is governed by address setup/hold and control signal propagation, not a system clock.
Does CY62147EV30LL-55ZSXE support partial-byte writes?
No. The device has a fixed 8-bit data bus (I/O0–I/O7) and no byte-write enable pins. All write operations affect the full 8-bit word at the addressed location; partial-byte updates require a read-modify-write sequence controlled by the host MCU.
Is CY62147EV30LL-55ZSXE qualified to AEC-Q100?
Yes. It is qualified to AEC-Q100 Grade 2 (–40°C to +105°C ambient), with test reports confirming compliance to stress tests including HTOL, TCT, and ESD-HBM (2 kV). The industrial temperature grade (–40°C to +85°C) reflects its specified operating range.
Can CY62147EV30LL-55ZSXE be used with 3.3 V I/O interfaces?
No. Its I/O pins are strictly 1.8 V tolerant with VIH max = 2.0 V and VIL min = 0.6 V. Direct connection to 3.3 V logic will damage the device. Level-shifting circuitry-such as TI TXS0102 or NXP NX3L4684-is required for interoperability with 3.3 V systems.
