Product details

Overview

FM28V202A-TG from Cypress Semiconductor is a 2-Mbit (128 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. It operates from 2.0 V to 3.6 V across –40 °C to +85 °C and replaces battery-backed SRAM in industrial logging, metering, and real-time event capture systems.

For engineers reviewing the FM28V202A-TG datasheet, FM28V202A-TG pinout, FM28V202A-TG application, or FM28V202A-TG equivalent, key selection criteria include NoDelay™ write capability, software-configurable sector write protection, TSOP-II package compatibility, and drop-in replacement feasibility for legacy 128K×16 SRAM designs without timing or power-supply redesign.

Technical Context

The FM28V202A-TG implements a parallel-access F-RAM core using ferroelectric capacitor-based storage cells, enabling true nonvolatility without write latency or wear leveling. Its architecture supports both CE- and WE-controlled read/write cycles, with page mode operation across four column addresses per row (A1–A0) and automatic pre-charge on upper address change (A16–A2).

It integrates software write-protection logic that divides memory into eight 16 K × 16 sectors, each individually configurable via a deterministic six-read/three-write address/command sequence. Sleep mode is activated by pulling ZZ low, reducing standby current to 120 µA while disabling all pins except ZZ.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	2 Mbit (128 K × 16), configurable as 256 K × 8 using UB/LB controls
Access Time	60 ns - enables direct substitution for standard 70-ns SRAM without bus timing adjustments
Write Endurance	10¹⁴ cycles - supports >1 million writes/day for 27 years without degradation
Data Retention	151 years at +85 °C - eliminates need for periodic refresh or backup power
Supply Voltage	2.0 V to 3.6 V - compatible with modern low-voltage microcontroller I/O domains
Operating Temperature	–40 °C to +85 °C - qualified for industrial-grade embedded control and instrumentation
Active Current	7 mA (typ) - reduces thermal load in dense PCB layouts with multiple memory devices

Pinout & Package

FM28V202A-TG is housed in a 44-pin thin small outline package (TSOP-II), 400-mil body width, surface-mount compatible with standard reflow profiles. Pin pitch is 0.8 mm; package meets RoHS Directive 2011/65/EU.

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
DQ0–DQ15	Bidirectional Data Bus	16-bit parallel I/O; UB/LB control byte-level directionality during reads/writes
WE	Write Enable	Rising edge triggers immediate nonvolatile write; falling edge latches new column address in page mode
CE	Chip Enable	Falling edge initiates memory cycle and latches full address; deassertion starts pre-charge
OE	Output Enable	Drives DQ bus only when LOW and valid data is ready; prevents bus contention transients
UB / LB	Byte Select Controls	Enable DQ15–DQ8 (UB) or DQ7–DQ0 (LB); both may be tied to GND if 16-bit operation is used exclusively
ZZ	Sleep Mode Input	Pull LOW to enter 120 µA sleep state; must be HIGH for all active operations
VDD / VSS	Power / Ground	Single 2.0–3.6 V supply; no separate I/O voltage required

Key Features

Feature	Design Value
NoDelay™ Write Architecture	Writes complete within same bus cycle as reads-no wait states, polling, or timeout handling required
Software-Configurable Sector Protection	Eight independent 16 K × 16 blocks protected via nonvolatile command sequence-no external hardware or fuses needed
SRAM Drop-In Compatibility	Industry-standard 128 K × 16 pinout and timing eliminates PCB redesign when replacing legacy SRAM or BBSRAM
Monolithic Nonvolatility	Eliminates battery, supercapacitor, and associated reliability risks-no rework, moisture sensitivity, or shock vulnerability
Page Mode Performance	30-ns cycle time for sequential column accesses within same row-accelerates burst logging and FIFO operations

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
CY14B102QN-SP	Same F-RAM technology, but 2-Mbit density in 48-pin SOIC; lacks TSOP-II footprint and has slower 70-ns access	Preferred for through-hole prototyping or legacy board upgrades where space allows larger package	Select when mechanical compatibility with existing SOIC sockets is required over surface-mount density
AT28HC256-15PU	EEPROM with 150-ns access, 100K endurance, requires 10-ms write cycles and polling	Acceptable only for infrequent configuration storage-not suitable for high-frequency logging or real-time buffering	Choose only if cost is primary constraint and write frequency remains below 100 writes/hour

Compared with CY14B102QN-SP and AT28HC256-15PU, FM28V202A-TG delivers superior write speed, endurance, and package compactness-making it optimal for space-constrained, high-write industrial systems where deterministic nonvolatility is mandatory.

FAQ

Is FM28V202A-TG pin-compatible with standard 128 K × 16 SRAMs?

Yes-FM28V202A-TG uses an industry-standard 44-pin TSOP-II footprint and identical signal naming (A0–A16, DQ0–DQ15, CE, OE, WE, UB, LB, ZZ). No PCB layout changes are needed for SRAM drop-in replacement, though OE timing margin should be verified per system clock rate.

Does FM28V202A-TG require external circuitry for write protection?

No-software write protection is fully integrated and nonvolatile. Each of the eight 16 K × 16 sectors is independently enabled/disabled via a documented six-read/three-write command sequence issued over the parallel bus; no external resistors, jumpers, or security ICs are required.

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 industrial temperature range (–40 °C to +85 °C). At –40 °C, 2.0 V ensures guaranteed 60-ns access time and 10¹⁴ endurance-no derating or voltage boost is necessary for cold-environment deployment.

Can FM28V202A-TG operate in page mode across row boundaries?

No-page mode is restricted to four column addresses (A1–A0) within a single row. Accessing a different row (change in A16–A2) forces pre-charge and resets page mode; the next access requires full address setup and incurs tRC or tWC delay, not tAAP.
