Product details
Overview
CY15B101N-ZS60XAT from Infineon Technologies (formerly Cypress) is a 1-Mbit automotive-grade ferroelectric RAM (F-RAM™) logically organized as 64K × 16, with SRAM-compatible parallel interface, 60-ns access time, and true nonvolatility enabling immediate data retention without write delay. It operates across –40 °C to +85 °C and delivers 1014 read/write endurance for high-cycle logging in engine control units.
For engineers reviewing the CY15B101N-ZS60XAT datasheet, CY15B101N-ZS60XAT pinout, CY15B101N-ZS60XAT application, or CY15B101N-ZS60XAT equivalent, key selection criteria include NoDelay™ write timing, byte-selectable 16-bit bus operation, TSOP-II package compatibility, and drop-in replacement capability for 64K × 16 SRAMs in safety-critical automotive systems.
Technical Context
The CY15B101N-ZS60XAT implements a ferroelectric memory array with eight 2048-row blocks and four-column page architecture, enabling sub-30-ns cycle time in page mode. Its CE- and WE-controlled dual-write protocol supports both SRAM-like random access and burst-aligned sequential writes without polling or wait states.
It features dedicated UB/LB byte enables for 8-bit sub-word access, ZZ sleep control for <120 µA standby current, and full SRAM pinout compliance-including A0–A15 address lines, DQ0–DQ15 bidirectional data bus, and standard CE/OE/WE controls-ensuring hardware-level interoperability with legacy SRAM-based designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 1 Mbit (64K × 16), configurable as 128K × 8 via UB/LB control |
| Access time | 60 ns (max), enabling direct replacement of 70-ns SRAMs without timing redesign |
| Write endurance | 1014 cycles - supports >10 years of continuous 100-Hz data logging at full bandwidth |
| Data retention | 151 years at +85 °C - eliminates battery backup and wear-leveling firmware overhead |
| Supply voltage | 2.0 V to 3.6 V - compatible with automotive 3.3-V rail and low-voltage microcontrollers |
| Operating temperature | –40 °C to +85 °C (Automotive-A grade) - qualified for under-hood ECU deployment |
| Package | 44-pin TSOP-II (400-mil), surface-mount, RoHS-compliant - matches industry-standard SRAM footprint |
Pinout & Package
44-pin Thin Small Outline Package (TSOP-II), 400-mil body width, 0.8-mm lead pitch, JEDEC MO-141AC compliant. Pin 1 index marked by notch or dot; top view shown in datasheet Figure 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address inputs | Fall edge of CE latches full 16-bit address; A1–A0 select column within 4-location page |
| DQ0–DQ15 | Bidirectional data bus | 16-bit parallel I/O; driven only when OE LOW and corresponding UB/LB asserted |
| WE | Write enable | Rising edge initiates write; falling edge latches new column address in page mode |
| CE | Chip enable | Falling edge latches address and starts memory cycle; may remain LOW for SRAM-style continuous access |
| OE | Output enable | Controls DQ bus drive; HI-Z when HIGH - prevents bus contention during invalid data windows |
| UB / LB | Upper/Lower byte select | Enable DQ15–DQ8 or DQ7–DQ0 independently; tied to GND if unused for full-word operation |
| ZZ | Sleep control | LOW enters ultra-low-power mode (<120 µA); must be HIGH before any access; tie to VDD if unused |
| VDD / VSS | Power / Ground | Single 2.0–3.6 V supply; decoupling required per automotive EMC standards |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ write architecture | Writes complete in same cycle as reads - no wait states, no polling, no firmware overhead |
| SRAM pinout and timing compatibility | Direct drop-in replacement for 64K × 16 asynchronous SRAMs without PCB or logic redesign |
| Page-mode 30-ns cycle time | Enables 33-MHz burst transfers across 4-column pages - critical for real-time CAN message buffering |
| Monolithic nonvolatility | Eliminates battery, supercapacitor, and associated rework - reduces BOM count and field failure modes |
| Automotive-A qualification | Validated per AEC-Q100 Grade 2; supports functional safety requirements in ASIL-B systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile parallel-memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FM25V10-G | 1-Mbit F-RAM, 44-pin TSOP-II, but 85 °C max operating temp only (industrial grade) | Lacks AEC-Q100 qualification; not approved for under-hood automotive use | Select only for non-automotive industrial control where extended temperature is not required |
| IS61WV102416BLL-10TLI | 1-Mbit battery-backed SRAM, same pinout and speed, but requires external battery and rework | Introduces moisture sensitivity, battery leakage risk, and end-of-life replacement complexity | Use only if existing design already uses BBSRAM and F-RAM redesign is not feasible |
Compared with FM25V10-G and IS61WV102416BLL-10TLI, the CY15B101N-ZS60XAT uniquely combines AEC-Q100 qualification, monolithic reliability, and true zero-delay writes - making it the only drop-in solution that satisfies both functional safety and long-term data integrity requirements in automotive ECUs.

FAQ
Is CY15B101N-ZS60XAT pin-compatible with standard 64K × 16 SRAMs?
Yes - it uses an industry-standard 44-pin TSOP-II footprint with identical A0–A15, DQ0–DQ15, CE, OE, and WE signal assignments. UB/LB pins map to standard byte-enable functions, and ZZ replaces NC or reserved pins on many SRAMs. No PCB redesign is needed for drop-in replacement.
Does CY15B101N-ZS60XAT require special write sequencing or command protocols?
No - it operates like an asynchronous SRAM: write cycles initiate on CE or WE transitions with no command codes, address setup delays, or status polling. Data written on the rising edge of WE is immediately nonvolatile, eliminating EEPROM-style write cycles and timeout handling.
Can CY15B101N-ZS60XAT be used in systems powered by 2.5-V rails?
Yes - its guaranteed operating range is 2.0 V to 3.6 V, including 2.5-V nominal supplies. All AC/DC specifications, including 60-ns access time and 1014 endurance, are validated across this full voltage range per datasheet Rev. *F testing conditions.
What happens if ZZ (sleep) is left floating during operation?
Leaving ZZ floating risks unintended entry into sleep mode due to noise coupling, causing bus lockup until ZZ is pulled HIGH. The datasheet explicitly requires ZZ to be tied to VDD if unused. A 10-kΩ pull-up resistor is recommended for robustness in automotive EMI environments.
