Product details

Overview

CY62146GE30-45ZSXI from Infineon Technologies is a 4-Mbit (256K × 16) low-power CMOS static RAM with 45 ns access time, 3.3 V supply voltage, and industrial temperature range (–40°C to +85°C), used in network interface cards and real-time data buffering.

For engineers reviewing the CY62146GE30-45ZSXI datasheet, CY62146GE30-45ZSXI pinout, CY62146GE30-45ZSXI application, or CY62146GE30-45ZSXI equivalent, key selection criteria include access time, standby current, byte-wide data bus support, and industrial-grade thermal stability.

Technical Context

This SRAM implements asynchronous read/write operation with separate chip enable (CE), output enable (OE), and write enable (WE) controls. It supports byte-wide access via UB/LB pins for 16-bit data bus partitioning.

The device uses standard TTL-compatible input thresholds and produces CMOS-level outputs. Standby current drops to 1 µA max at V_CC = 3.3 V, enabling low-power hold mode in embedded controllers.

Key Specifications

Memory Size	4 Mbit (256K × 16) - supports 256 KB of word-addressable data storage
Access Time	45 ns - enables direct interfacing with 22 MHz microcontrollers without wait states
Supply Voltage	3.3 V ± 0.3 V - compatible with modern low-voltage logic families and I/O standards
Standby Current	1 µA max - allows battery-backed operation in power-constrained systems
Operating Temperature	–40°C to +85°C - qualified for industrial control and telecom infrastructure environments
Data Bus Width	16-bit - provides word-aligned memory access for DSPs and 16-bit microprocessors

Pinout & Package

Supplied in a 32-pin SOIC (Small Outline Integrated Circuit) package with 0.4 mm lead pitch and JEDEC MS-012AC footprint.

Pin/Terminal	Circuit Role	Design Meaning
A0–A17	Address Inputs	18-bit address bus supporting 256K word locations
DQ0–DQ15	Data Input/Output	Bi-directional 16-bit data bus with internal tristate control
CE#	Chip Enable	Active-low global enable controlling device selection and power state
OE#	Output Enable	Active-low control for data bus output drivers only
WE#	Write Enable	Active-low signal gating write cycles; high = read mode
UB#/LB#	Upper/Lower Byte Control	Enables byte-select writes to DQ8–DQ15 or DQ0–DQ7 independently
V_CC, V_SS	Power & Ground	Single 3.3 V supply with dedicated ground return path

Key Features

Feature	Design Value
Low-power standby mode	1 µA max ICCSB enables extended battery life in portable instrumentation
Byte-wide write control	Independent UB#/LB# pins allow selective 8-bit updates without full-word rewrite
TTL-compatible inputs	V_IL = 0.8 V, V_IH = 2.0 V ensures reliable interfacing with legacy 3.3 V microcontrollers
Industrial temperature grade	–40°C to +85°C operation validated per AEC-Q200 stress test conditions

Equivalent & Alternatives

The following parts are listed as comparable options for similar SRAM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IS61LV25616AL-10TLI	10 ns faster access (35 ns), higher ICC active current (45 mA vs 35 mA)	Better suited for high-throughput video frame buffers where latency dominates power budget	Select when system clock > 28 MHz requires tighter timing margin
MT48LC4M16A2P-6A:G	Synchronous SDRAM architecture, 6 ns CL, requires clock and refresh management	Used in bandwidth-intensive applications like baseband processing where burst transfers outweigh setup complexity	Choose only if existing controller supports SDRAM protocol and refresh circuitry

Compared with IS61LV25616AL-10TLI and MT48LC4M16A2P-6A:G, CY62146GE30-45ZSXI offers simpler asynchronous interface and lower active power, making it optimal for cost-sensitive industrial controllers where deterministic latency matters more than peak bandwidth.

FAQ

Is CY62146GE30-45ZSXI pin-compatible with CY62146EV30-45ZSXI?

Yes. Both share identical 32-pin SOIC package, pin functions, and electrical characteristics. The 'G' suffix denotes green (halogen-free) packaging compliance, while 'V' indicates standard RoHS-compliant packaging-no layout or schematic changes required for substitution.

What is the maximum operating frequency supported by the address bus?

The device does not operate on a clock; it is asynchronous. Address setup and hold times are specified at 25 ns minimum, allowing reliable operation with microcontrollers running up to 22 MHz bus clocks without external wait-state generation.

Does this SRAM require periodic refresh cycles?

No. CY62146GE30-45ZSXI is a true static RAM and retains data indefinitely as long as V_CC is applied and within specification. No refresh circuitry or timing overhead is needed, unlike DRAM or PSRAM devices.

Can UB# and LB# be asserted simultaneously during a write operation?

Yes. Asserting both UB# and LB# low enables full 16-bit write operation. The device internally combines the signals to activate all DQ lines; no conflict or undefined behavior occurs when both are active.
