Product details
Overview
CY62167EV30LL-45ZXI from Cypress Semiconductor is an automotive-grade 16-Mbit CMOS static RAM organized as 1M × 16 or 2M × 8, operating at 45 ns access time with 2.2–3.6 V supply, ultra-low standby current (1.5 µA typ), and automatic power-down capability. It serves as main memory or buffer in engine control units, ADAS domain controllers, and infotainment head units requiring AEC-Q100 compliance and extended temperature operation.
For engineers reviewing the CY62167EV30LL-45ZXI datasheet, CY62167EV30LL-45ZXI pinout, CY62167EV30LL-45ZXI application, or CY62167EV30LL-45ZXI equivalent, key selection criteria include configurable x16/x8 bus width, TSOP I and VFBGA package options, automotive-A temperature range (–40 °C to +85 °C), MoBL® low-power architecture, and dual chip enable (CE1/CE2) for seamless memory expansion.
Technical Context
The device implements a dual-bank SRAM array with independent byte enables (BHE/BLE) and two active-low chip enables (CE1/CE2), enabling flexible memory mapping and interleaved access. Its automatic power-down logic reduces ICC by >99% when CE1 is HIGH or CE2 is LOW or both BHE and BLE are HIGH - verified under f = 0 conditions per ISB1 specification.
It supports two physical configurations: 48-pin TSOP I (with BYTE pin tied to VCC for 1M×16 or VSS for 2M×8) and 48-ball VFBGA (where H6 is NC but usable for future density upgrades). All timing parameters - including tAA (45 ns), tDOE (22 ns), and tHZOE (18 ns) - are guaranteed over the full automotive-A voltage and temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16 or 2M × 8 configuration) |
| Access Time | 45 ns - guarantees deterministic read latency in real-time ECU firmware execution |
| Supply Voltage | 2.2 V to 3.6 V - compatible with automotive 3.3 V rail and brown-out tolerant down to 2.2 V |
| Standby Current | 1.5 µA typical / 12 µA max - enables multi-year battery-backed data retention in always-on modules |
| Operating Current | 2.2 mA typical at 1 MHz - supports low-duty-cycle logging without thermal derating |
| Temperature Range | –40 °C to +85 °C (Automotive-A grade) - qualified per AEC-Q100 Rev G for under-hood deployment |
| Package | 48-pin TSOP I (Z suffix) - surface-mount compatible with standard reflow profiles and board-level test access |
Pinout & Package
Package: 48-pin TSOP I (Type I, 12 mm × 20 mm, 0.5 mm pitch), RoHS-compliant, Pb-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 1M-word (x16) or 2M-word (x8) addressing; A20 appears on I/O15 pin in x8 mode |
| I/O0–I/O15 | Bi-directional Data Bus | 16-bit parallel interface; high-impedance during deselect, OE HIGH, or write cycles; split into I/O0–I/O7 (BLE-controlled) and I/O8–I/O15 (BHE-controlled) |
| CE1, CE2 | Chip Enable Inputs | Active-low dual CE architecture enables hierarchical memory decoding; CE1 HIGH or CE2 LOW forces automatic standby mode |
| OE | Output Enable | Controls output drivers only; does not affect internal power state - valid only when CE1/CE2 assert selection |
| WE | Write Enable | Active-low signal initiating write cycle; timing-critical path with tPWE ≥ 35 ns minimum pulse width |
| BHE, BLE | Byte Enable Inputs | Independent 8-bit write masking: BLE LOW writes I/O0–I/O7; BHE LOW writes I/O8–I/O15; both HIGH places I/Os in Hi-Z |
| BYTE | Bus Width Configuration | Must be tied to VCC for 1M×16 mode or VSS for 2M×8 mode; determines pin function of I/O8–I/O14 and A20 routing |
| VCC, VSS | Power Supply | Single 2.2–3.6 V supply; separate VSS pins reduce ground bounce in high-speed burst reads |
Key Features
| Feature | Design Value |
|---|---|
| Configurable x16/x8 Organization | Single part supports two memory map topologies via BYTE pin strap - eliminates BOM variants for platform reuse |
| MoBL® Ultra-Low Power Architecture | 1.5 µA typical ISB1 enables >10-year data retention on coin-cell backup in telematics black boxes |
| Dual Chip Enable (CE1/CE2) | Enables seamless 32-bit or 64-bit memory expansion using standard address decode logic without glue logic |
| Automatic Power-Down | Hardware-triggered transition to <12 µA standby when address bus stabilizes - no software intervention required |
| Automotive-A Qualification | Fully qualified to AEC-Q100 Grade 2 with guaranteed parametric performance across –40 °C to +85 °C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed automotive SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV102416BLL-10MLI | 10 ns faster (35 ns), wider voltage (2.2–3.6 V), but higher ISB (25 µA max) and no automatic power-down logic | Preferred for non-automotive industrial controllers where speed outweighs standby power | Select when system-level timing budget requires <35 ns tAA and thermal margin allows higher ICC |
| AS6C1008-55TIN | Slower (55 ns), narrower voltage (2.7–3.6 V), lower density (8 Mbit), but AEC-Q100 qualified and pin-compatible in TSOP I | Suitable for legacy ECU redesigns where footprint compatibility is mandatory and 45 ns is not required | Choose for drop-in replacement in existing 8-Mbit designs needing AEC-Q100 upgrade without layout change |
Compared with IS61WV102416BLL-10MLI and AS6C1008-55TIN, CY62167EV30LL-45ZXI uniquely balances automotive qualification, 45 ns speed, and MoBL® ultra-low standby - making it optimal for new designs prioritizing battery life and functional safety compliance over raw speed or legacy compatibility.

FAQ
What is the function of the BYTE pin on CY62167EV30LL-45ZXI?
The BYTE pin configures the memory organization: tie to VCC for 1M × 16 mode (standard 16-bit interface), or tie to VSS for 2M × 8 mode (8-bit interface with A20 routed to I/O15). In TSOP I packages, this pin must be externally strapped - no internal pull-up/down - and determines pin functionality of I/O8–I/O14 and address width.
Does CY62167EV30LL-45ZXI require external refresh circuitry?
No. As a static RAM, CY62167EV30LL-45ZXI retains data indefinitely while powered and selected, with no refresh cycles needed. Data retention continues down to VCC = 1.5 V in standby mode (ICCDR ≤ 10 µA), confirmed per page 6 of datasheet 38-05446 Rev. *Q.
How does automatic power-down activate in CY62167EV30LL-45ZXI?
Automatic power-down triggers when any of these occurs: CE1 goes HIGH, CE2 goes LOW, or both BHE and BLE go HIGH. This reduces ICC to ≤12 µA (ISB1) without software intervention - verified under f = 0 conditions with CMOS-level inputs per Electrical Characteristics table on page 4.
Can CY62167EV30LL-45ZXI operate at 2.5 V supply?
Yes. The device is fully specified from 2.2 V to 3.6 V, including all AC timing (tAA = 45 ns max), DC parameters (VOH/VOL), and power consumption (ISB1 = 1.5 µA typ) at 2.5 V - explicitly validated in the Operating Range table on page 4 of datasheet 38-05446 Rev. *Q.
