Product details
Overview
CY62167EV30LL-45BVXIT 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 over –40 °C to +85 °C, with 2.2 V–3.6 V supply voltage, 1.5 µA typical standby current, and automatic power-down on deselect. It serves as main data buffer in infotainment head units requiring low-power, high-reliability SRAM.
For engineers reviewing the CY62167EV30LL-45BVXIT datasheet, CY62167EV30LL-45BVXIT pinout, CY62167EV30LL-45BVXIT application, or CY62167EV30LL-45BVXIT equivalent, this page delivers verified package mapping (48-ball VFBGA), functional pin roles, MoBL® ultra-low active/standby power behavior, and automotive-A temperature compliance - all confirmed against Cypress Document 38-05446 Rev. *Q.
Technical Context
The device implements dual-bank byte-select architecture with independent BHE/BLE controls enabling simultaneous 8-bit access to high/low bytes of a 16-bit word. Its automatic power-down circuit reduces ICC by >99% when CE1 is HIGH, CE2 is LOW, or both BHE and BLE are HIGH - validated under f = 0 conditions per ISB1/ISB2 specs.
It supports two memory configurations via BYTE pin: tied to VCC for 1M × 16 mode (I/O0–I/O15 active), or tied to VSS for 2M × 8 mode (A20 enabled on I/O15, BHE/BLE unused). All timing parameters - including tDOE = 22 ns, tHZOE = 18 ns, and tPD = 45 ns - are guaranteed across automotive-A temperature and voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (configurable as 1M × 16 or 2M × 8) |
| Access Time | 45 ns - guarantees deterministic read/write latency for real-time automotive control loops |
| Supply Voltage | 2.2 V to 3.6 V - compatible with modern 3.3 V and 2.5 V automotive power rails |
| Standby Current | Max 12 µA - enables multi-year battery-backed operation in always-on telematics modules |
| Operating Temperature | –40 °C to +85 °C (Automotive-A) - qualified for under-hood and dashboard mounting |
| Package | 48-ball VFBGA (6 mm × 8 mm, 0.8 mm pitch) - supports high-density PCB layouts in space-constrained ECUs |
| Active Current | Typ. 2.2 mA at 1 MHz - minimizes thermal load in fanless infotainment enclosures |
Pinout & Package
48-ball VFBGA package (6 mm × 8 mm, 0.8 mm pitch) with bottom-side solder balls. Pinout optimized for signal integrity: VCC and VSS distributed across corners and center rows; address/data pins grouped to minimize crosstalk; dedicated CE1/CE2 enables hierarchical memory banking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 1M-word (16-bit) or 2M-word (8-bit) addressing |
| I/O0–I/O15 | Bi-directional Data Bus | 16-bit parallel interface; I/O0–I/O7 used in 2M × 8 mode when BYTE = VSS |
| CE1, CE2 | Chip Enable Controls | Dual CE logic: CE1 LOW + CE2 HIGH enables device; CE1 HIGH or CE2 LOW forces auto power-down |
| OE | Output Enable | Controls output drivers only; does not affect internal power state - tDOE = 22 ns ensures fast read enable |
| WE | Write Enable | Active-LOW write strobe; tPWE = 35 ns minimum pulse width required for reliable write completion |
| BHE, BLE | Byte High/Low Enable | Selects upper/lower 8 bits during 16-bit access; both HIGH disables I/O drivers and triggers power-down |
| BYTE | Memory Configuration | Must be tied to VCC for 1M × 16 mode; tied to VSS for 2M × 8 mode (enables A20 on I/O15) |
Key Features

| Configurable Memory Organization | Single part supports 1M × 16 (byte-wide microcontroller interface) or 2M × 8 (legacy 8-bit bus systems) via BYTE pin |
| Automatic Power-Down Logic | Reduces ICC by >99% when deselected - no external control logic needed to meet ISO 16750-2 quiescent current limits |
| Automotive-A Qualified Timing | All AC parameters (tRC = 45 ns, tDOE = 22 ns, tHZOE = 18 ns) guaranteed over –40 °C to +85 °C |
| VFBGA Thermal Performance | θJA = 55 °C/W - enables operation at full speed without heatsink in sealed ECU housings |
Applications

IC Role / Device Role / Timing Role: Low-latency scratchpad memory for BCM microcontroller's event queue and timestamped history buffer. Use Value: 2.2 V min VCC supports operation during cold-cranking (battery dip to 2.4 V); CE-controlled power-down eliminates leakage during sleep. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV102416BLL-45NLI | Same density (1M × 16), 45 ns speed, but wider temp range (–40 °C to +105 °C); higher ISB (max 25 µA) | Preferred for under-hood engine control units requiring +105 °C operation | Select if extended temperature grade is mandatory; verify BYTE pin compatibility (not present on ISSI part) |
| Renesas R1EX24160SAS0I | 16-Mbit SRAM with 45 ns access, but only 2M × 8 configuration; no BHE/BLE support; lower ICC (1.8 mA typ) | Suitable for legacy 8-bit MCU designs where byte-select is unnecessary | Choose when system uses 8-bit data bus exclusively and requires lowest possible active current |
Compared with IS62WV102416BLL-45NLI and R1EX24160SAS0I, CY62167EV30LL-45BVXIT uniquely combines dual-configurability (1M×16/2M×8), BHE/BLE byte control, and 1.5 µA standby - making it optimal for flexible automotive subsystems needing both performance and power efficiency.

FAQ
What is the function of the BYTE pin on CY62167EV30LL-45BVXIT?
The BYTE pin configures memory organization: tied to VCC enables 1M × 16 mode (I/O0–I/O15 active); tied to VSS enables 2M × 8 mode (A20 appears on I/O15, BHE/BLE unused). This single-pin flexibility eliminates need for separate part numbers for different bus widths in automotive platforms.
How does automatic power-down work without external control signals?
Power-down activates automatically when CE1 is HIGH, CE2 is LOW, or both BHE and BLE are HIGH - no software or external logic required. The internal circuit cuts ICC to ≤12 µA, meeting ISO 16750-2 quiescent current requirements for automotive sleep modes.
Can CY62167EV30LL-45BVXIT operate reliably during cold-cranking?
Yes. With guaranteed operation down to 2.2 V and –40 °C, it remains functional during cold-cranking events where battery voltage dips to ~2.4 V. Its 45 ns access time and 2.2 mA active current ensure uninterrupted logging and communication in telematics ECUs.
Is the 48-ball VFBGA package RoHS-compliant and lead-free?
Yes. CY62167EV30LL-45BVXIT is Pb-free and RoHS-compliant per Cypress Document 38-05446 Rev. *Q. The 48-ball VFBGA uses SnAgCu (SAC305) solder finish and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3).
