Product details

Overview

CY15B102N-ZS60XA from Cypress Semiconductor is a 2-Mbit (128K × 16) automotive-grade ferroelectric RAM (F-RAM) with SRAM-compatible parallel interface, 60-ns access time, 10¹⁴ read/write endurance, and 151-year data retention at –40 °C to +85 °C. It serves as nonvolatile memory in safety-critical automotive control modules requiring rapid, reliable writes without backup batteries.

For engineers reviewing the CY15B102N-ZS60XA datasheet, CY15B102N-ZS60XA pinout, CY15B102N-ZS60XA application, or CY15B102N-ZS60XA equivalent, key selection factors include NoDelay™ write timing, software-configurable sector write protection, TSOP-II package compatibility, and drop-in replacement capability for 128K × 16 SRAMs in CAN/LIN gateway loggers and ADAS event recorders.

Technical Context

The CY15B102N-ZS60XA implements a ferroelectric memory array organized as eight 16K × 16 blocks, each supporting page-mode access via A1–A0 column addressing. Its SRAM-like operation eliminates write latency and removes need for polling or erase cycles.

It supports dual write control modes (CE- and WE-initiated), software-programmable block-level write protection using a six-read/three-write address sequence, and low-power sleep mode activated by the ZZ pin. All operations are guaranteed across the Automotive-A temperature range (–40 °C to +85 °C) with VDD = 2.0 V to 3.6 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory size	2 Mbit (128K × 16), configurable as 256K × 8 using UB/LB byte enables
Access time	60 ns - enables direct substitution for standard 128K × 16 SRAMs without timing redesign
Endurance	10¹⁴ read/write cycles - supports continuous logging in vehicle black-box recorders
Data retention	151 years at +85 °C - ensures nonvolatile storage over full automotive service life without refresh
Supply voltage	2.0 V to 3.6 V - compatible with modern low-voltage automotive power domains
Operating temperature	–40 °C to +85 °C (Automotive-A grade) - qualified for engine bay and cabin control units
Active current	7 mA (typ) - reduces thermal load in space-constrained ECUs

Pinout & Package

Package: 44-pin Thin Small Outline Package (TSOP-II), 400-mil width, RoHS-compliant surface-mount.

Pin/Terminal	Circuit Role	Design Meaning
A0–A16	Address inputs	17-bit address bus latched on CE falling edge; A1–A0 enable 4-column page-mode access per row
DQ0–DQ15	Data I/O bus	16-bit bidirectional data path; driven only when OE LOW and corresponding UB/LB asserted
WE	Write Enable	Rising edge triggers immediate nonvolatile write; falling edge latches new column address in page mode
CE	Chip Enable	Falling edge latches full address and initiates read/write cycle; controls precharge when HIGH
OE	Output Enable	Controls DQ bus drive; HI-Z when HIGH, preventing bus contention during invalid data windows
UB / LB	Byte select	Enable upper (DQ15–DQ8) or lower (DQ7–DQ0) data byte; allow 8-bit access or 256K × 8 configuration
ZZ	Sleep mode	LOW enters ultra-low-power state (120 µA standby); must be HIGH for all active operations
VDD / VSS	Power / Ground	Single 2.0–3.6 V supply; VSS must connect to system ground plane for noise immunity

Key Features

Feature	Design Value
NoDelay™ writes	Immediate nonvolatile storage on WE rising edge - eliminates write latency and polling overhead in real-time logging
Software write-protect	Eight independent 16K × 16 sectors protected via nonvolatile command sequence - prevents firmware corruption during ECU reprogramming
Page-mode operation	30-ns cycle time for sequential column accesses within same row - accelerates burst logging of sensor frames
SRAM pinout compatibility	Industry-standard 128K × 16 parallel interface - enables drop-in replacement without PCB or firmware changes
Monolithic reliability	No battery, capacitor, or external support components required - simplifies BOM and improves long-term field reliability

Applications

ADAS Event Recorder

Powertrain Control Unit Log Buffer

Use Scenario: Continuous capture of radar/lidar timestamped frames during collision events.

IC Role / Device Role / Timing Role: Nonvolatile frame buffer storing pre- and post-trigger snapshots with sub-microsecond write commit.

Use Value: Eliminates risk of data loss during power interruption; sustains 10⁶+ write cycles per hour without degradation.

Use Scenario: Storing misfire counts, knock sensor history, and OBD-II freeze-frame data across ignition cycles.

IC Role / Device Role / Timing Role: Persistent parameter storage updated every 10 ms during engine run, surviving cold starts.

Use Value: Guarantees 151-year data retention at under-hood temperatures; avoids EEPROM wear-out in high-durability applications.

Body Control Module Configuration

Infotainment System Crash Log

Use Scenario: Retaining user preferences (seat position, mirror angle, lighting profiles) after battery disconnect.

IC Role / Device Role / Timing Role: Low-voltage (2.0 V) nonvolatile storage accessed during wake-up initialization.

Use Value: Operates down to 2.0 V - captures settings even during brown-out conditions where SRAM would fail.

Use Scenario: Capturing stack traces and register dumps following infotainment OS crashes.

IC Role / Device Role / Timing Role: High-speed write buffer accepting burst data from ARM Cortex-A core before safe shutdown.

Use Value: 60-ns access + NoDelay™ write enables full context capture in <100 µs - critical for root-cause analysis.

Equivalent & Alternatives

The following parts are listed as comparable options for similar nonvolatile parallel memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
FM22L16-60-TG	2-Mbit F-RAM in 48-pin TSOPII; 60-ns access; 10¹⁴ endurance; VDD = 2.7–3.6 V	Requires 2.7 V minimum - not suitable for 2.0–2.6 V automotive domains	Select if system uses ≥2.7 V rail and needs extended temperature screening beyond Automotive-A
AT25DF041A-SHN-B	4-Mbit SPI NOR Flash; 85 MHz clock; 100k program/erase cycles; no byte-write capability	Serial interface requires firmware driver rewrite; no true SRAM drop-in replacement	Choose only when board space is constrained and parallel bus unavailable; accept write latency and endurance limits

Compared with FM22L16-60-TG and AT25DF041A-SHN-B, CY15B102N-ZS60XA uniquely delivers 2.0 V operation, true SRAM pinout compatibility, and unlimited write endurance - making it the only viable option for high-frequency, low-voltage automotive logging where reliability and timing predictability are non-negotiable.

FAQ

Is CY15B102N-ZS60XA pin-compatible with standard 128K × 16 SRAMs?

Yes - it uses an industry-standard 44-pin TSOP-II footprint and identical signal mapping (A0–A16, DQ0–DQ15, CE, WE, OE, UB, LB, ZZ, VDD, VSS). No PCB redesign is needed; only firmware verification of timing margins and write-protection behavior is required for migration.

Does CY15B102N-ZS60XA require external hardware for write protection?

No - it implements fully software-controlled, nonvolatile sector write protection. Protection is configured via a specific six-read/three-write address/data sequence issued over the parallel bus; no external WP pins or resistors are needed.

What is the minimum VDD voltage for reliable operation at –40 °C?

The device is specified for full functionality down to 2.0 V across the entire Automotive-A temperature range (–40 °C to +85 °C). At –40 °C, 2.0 V operation is guaranteed per DC electrical characteristics in Rev. *D datasheet, Table 9.

Can CY15B102N-ZS60XA be used in place of battery-backed SRAM without modifying system power architecture?

Yes - it eliminates batteries entirely. The monolithic F-RAM design draws only 120 µA in sleep mode and requires no backup power circuitry, capacitor hold-up, or battery monitoring logic - reducing BOM cost and improving long-term field reliability.
