Product details

Overview

CY62167DV30LL-45ZXIT from Cypress Semiconductor is a 16-Mbit (1M × 16 or 2M × 8) MoBL® CMOS static RAM with 45 ns access time, 2.2–3.6 V supply range, and ultra-low active current (18.5 mA at f_Max). It supports byte-wide write enable via BHE/ BLE, automatic CE-based power-down, and operates across –40°C to +85°C for industrial portable memory applications.

For engineers reviewing the CY62167DV30LL-45ZXIT datasheet, CY62167DV30LL-45ZXIT pinout, CY62167DV30LL-45ZXIT application, or CY62167DV30LL-45ZXIT equivalent, key selection criteria include TSOP I package compatibility, dual-configurable density (1M×16/2M×8), sub-25 µA standby current, MoBL® low-power architecture, and industrial temperature support.

Technical Context

This SRAM implements a high-speed, low-voltage CMOS core with separate Byte High Enable (BHE) and Byte Low Enable (BLE) inputs for independent 8-bit writes, and dual chip enables (CE1/CE2) enabling flexible memory expansion and hierarchical select control. The device uses address-controlled and OE-controlled read cycles with guaranteed tAA = tACE = 45 ns.

Power management includes automatic CE-triggered power-down reducing ICC to 2.5 µA typical, plus data retention down to V_DR = 1.5 V with I_CCDR ≤ 10 µA. All timing parameters are specified under 30 pF load and 1 V/ns edge rates per JEDEC-compliant AC test conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	16 Mbit (configurable as 1M × 16 or 2M × 8)
Access Time	45 ns - guarantees full-speed operation up to ~22 MHz bus frequency
V_CC Range	2.2 V – 3.6 V - compatible with 2.5 V and 3.3 V logic domains without level shifters
I_CC Active (f_Max)	18.5 mA typical - enables battery-powered operation with predictable peak current draw
I_SB2 Standby	2.5 µA typical - supports multi-week data retention in sleep modes
Operating Temp	–40°C to +85°C - qualified for industrial-grade embedded systems
tHZOE / tHZCE	15 ns max - ensures fast output disable for bus sharing and multiplexed data paths

Pinout & Package

Package: 48-pin TSOP I (Type I, forward pinout), RoHS-compliant, surface-mountable with 0.5 mm pitch.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ISSI IS62WV102416BLL-45NLI	Same density, 45 ns, 2.5–3.6 V; higher standby current (15 µA typ); no BYTE pin or 2M×8 mode	Lacks configurable organization - requires fixed 1M×16 layout; less flexible for legacy 8-bit bus upgrades	Select when strict 1M×16 usage is confirmed and lower ISB2 is not required.
ON Semiconductor MC14LC5480DW	16-Mbit, 55 ns, 4.5–5.5 V only; TTL-compatible; no low-voltage or MoBL® power features	Requires level translation for 3.3 V systems; unsuitable for battery operation due to 5 V minimum VCC	Choose only for legacy 5 V industrial designs where voltage compatibility outweighs power savings.

Compared with IS62WV102416BLL-45NLI and MC14LC5480DW, CY62167DV30LL-45ZXIT uniquely delivers 2.2 V operation, sub-3 µA standby, and hardware-switchable 1M×16/2M×8 modes - making it the sole option for power-constrained, multi-bus-compatible portable industrial memory.

FAQ

What is the function of the BYTE pin on CY62167DV30LL-45ZXIT?

The BYTE pin configures memory organization: tied to VCC for 1M × 16 mode (standard), or to VSS for 2M × 8 mode (reassigning Pin 45 as A20). In 2M×8 mode, BHE, BLE, and I/O8–I/O14 become no-connect; only I/O0–I/O7 remain active. This hardware-selectable feature avoids external logic or firmware changes.

Does CY62167DV30LL-45ZXIT support true 3.3 V-only operation?

Yes - it operates across 2.2 V to 3.6 V, fully compliant with 3.3 V ±10% (2.97–3.63 V) supply rails. All AC/DC specifications, including 45 ns access time and 18.5 mA I_CC, are guaranteed at V_CC = 3.0 V and 3.3 V. No derating is required within this range.

How does automatic power-down work without external control signals?

Power-down activates automatically when CE1 is HIGH or CE2 is LOW - no clock, timer, or software command needed. Internal circuitry reduces ICC to 2.5 µA typical by gating core array bias and disabling drivers. Recovery time (t_PU) is 0 ns, enabling immediate access upon re-enable.

Can CY62167DV30LL-45ZXIT be used in place of older 5 V SRAMs like the 6264?

No - it is not pin- or voltage-compatible with 5 V SRAMs. Its 2.2–3.6 V operation, TSOP I footprint, and dual CE architecture differ fundamentally from 28-pin DIP 5 V parts. Direct replacement requires board redesign, level translation, and timing validation due to different access protocols and enable logic.
