Product details

Overview

FM28V102A-TG from Cypress Semiconductor is a 1-Mbit (64 K × 16) ferroelectric RAM (F-RAM) nonvolatile memory with SRAM-compatible parallel interface, 60-ns access time, 10¹⁴ read/write endurance, and 151-year data retention at +85 °C - deployed in industrial data logging, metering, and real-time event capture systems where rapid, reliable nonvolatile writes are critical.

For engineers reviewing the FM28V102A-TG datasheet, FM28V102A-TG pinout, FM28V102A-TG application, or FM28V102A-TG equivalent, key selection criteria include NoDelay™ write architecture, TSOP-II 44-pin compatibility with legacy SRAM footprints, byte-selectable 16-bit bus operation, and industrial −40 °C to +85 °C temperature range compliance.

Technical Context

The FM28V102A-TG implements a ferroelectric capacitor-based memory array organized as 64 K × 16 words, enabling true nonvolatile storage without write latency or wear leveling. Its control logic supports both CE-initiated and WE-initiated read/write cycles, with page mode addressing via A1–A0 for sub-30-ns cycle times within the same row.

It features dual byte enable (UB/LB) for 128 K × 8 reconfiguration, sleep mode activation via ZZ pin (3 µA typical), and SRAM-equivalent timing - including tAA = 60 ns, tRC = 90 ns, and no data polling requirement - making it functionally transparent in existing SRAM-based address/data/control buses.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory density	1 Mbit (64 K × 16), configurable as 128 K × 8 using UB/LB controls
Access time	60 ns - enables direct replacement of 70-ns SRAMs without timing redesign
Write endurance	10¹⁴ cycles - supports >100 million writes/day for 27 years in continuous logging
Data retention	151 years at +85 °C - exceeds industrial lifetime requirements without battery backup
Supply voltage	2.0 V to 3.6 V - compatible with 2.5 V and 3.3 V system rails
Operating temperature	−40 °C to +85 °C - qualified for uncontrolled industrial environments
Active current	7 mA (typ) - matches SRAM power profile during burst access

Pinout & Package

FM28V102A-TG is housed in a 44-pin thin small outline package (TSOP-II, 400-mil width), surface-mount compatible with standard reflow profiles and IPC-7351 land patterns.

Pin/Terminal	Circuit Role	Design Meaning
A15–A0	Address inputs	16-bit address bus latched on CE falling edge; A1–A0 enable page mode column access
DQ15–DQ0	Data I/O lines	16-bit bidirectional bus; 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; may remain LOW for SRAM-like continuous access
OE	Output enable	Controls DQ bus drive; HI-Z when HIGH, eliminating bus contention and supply transients
UB / LB	Byte select	Enable DQ15–DQ8 (UB) or DQ7–DQ0 (LB); support 128 K × 8 configuration or independent byte writes
ZZ	Sleep mode	LOW activates 3 µA sleep mode; must be HIGH before any access; tied to VDD if unused
VDD / VSS	Power / ground	Single 2.0–3.6 V supply; decoupling required per AC switching specs (tRC = 90 ns)

Key Features

Feature	Design Value
NoDelay™ write architecture	Writes complete in single bus cycle with no latency, eliminating EEPROM-style polling or SRAM battery management
SRAM pinout and timing compatibility	Industry-standard 64 K × 16 parallel interface allows drop-in replacement without PCB or firmware changes
Page mode operation	30-ns cycle time within same row using A1–A0, enabling high-throughput sequential logging
Monolithic nonvolatility	Eliminates external battery, capacitor, or controller - reduces BOM count and field failure modes
Industrial-grade reliability	Qualified to −40 °C to +85 °C with RoHS-compliant TSOP-II package and 10¹⁴ endurance

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY14B101P-BA25XI	Same F-RAM technology, but 1-Mbit ×8 organization; requires bus-width redesign	Lacks native 16-bit DQ interface; not pin-compatible; needs UB/LB logic removal	Select only when system uses 8-bit data path and board layout permits trace reroute
IS61LV51216AL-10TLI	Battery-backed SRAM; 10 ns faster access but limited to 10⁶ write cycles and battery dependency	Requires external lithium coin cell, temperature derating, and end-of-life battery replacement planning	Choose only for legacy designs already committed to BBSRAM infrastructure and low-write-frequency use cases

Compared with CY14B101P-BA25XI and IS61LV51216AL-10TLI, FM28V102A-TG uniquely delivers 16-bit SRAM pinout compatibility, 10¹⁴ endurance, and monolithic nonvolatility - eliminating both bus redesign and battery management overhead in new industrial designs.

FAQ

Is FM28V102A-TG a direct pin-for-pin replacement for standard 64 K × 16 SRAMs?

Yes - it uses identical 44-pin TSOP-II footprint and industry-standard control signals (CE, WE, OE, UB, LB). Address and data timing align with 70-ns SRAMs, and CE may remain LOW indefinitely like an SRAM. No PCB redesign or glue logic is needed for migration.

Does FM28V102A-TG require special write sequencing or command protocols?

No - it operates as a true parallel memory with no instruction set or command decoding. Writes occur on the rising edge of WE (or falling edge of CE in CE-controlled mode), with data stored immediately and nonvolatily. No polling, delays, or erase cycles are required.

How does the ZZ (sleep) pin affect system power-up sequence?

ZZ must be held HIGH during power-up and remain HIGH until VDD stabilizes above 2.0 V. If pulled LOW prematurely, the device enters sleep mode and ignores CE/WE/OE until ZZ returns HIGH and tZZEX (100 ns max) elapses. Tie ZZ to VDD via 10-kΩ resistor if unused.

Can FM28V102A-TG be used in 128 K × 8 configurations?

Yes - by asserting UB and LB independently and wiring DQ15–DQ8 and DQ7–DQ0 to separate 8-bit buses, the device maps to 128 K × 8. Address A0 becomes the LSB, and A1–A16 form the full 17-bit address. System logic must manage byte-enable timing per the datasheet truth table.
