Product details

Overview

FM28V202A-TGTR 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 at +85 °C. It serves as a direct replacement for battery-backed SRAM in industrial data logging, metering, and real-time event capture systems where rapid, frequent writes are required without write delay.

For engineers reviewing the FM28V202A-TGTR datasheet, FM28V202A-TGTR pinout, FM28V202A-TGTR application, or FM28V202A-TGTR equivalent, key selection criteria include its NoDelay™ write architecture, software-configurable sector write protection, TSOP-II 44-pin package compatibility, and operation across –40 °C to +85 °C without external battery or capacitor support.

Technical Context

The FM28V202A-TGTR implements a ferroelectric memory array organized as eight 16 K × 16 blocks, each supporting page-mode reads/writes with 30-ns cycle time using A1–A0 column addressing. Its control logic accepts CE- or WE-initiated cycles, with address latching on CE fall and write completion on WE rise-enabling true single-cycle nonvolatile writes.

It features software-programmable block-level write protection via a deterministic six-read/three-write address/command sequence, retaining protection state without power. Sleep mode is entered via ZZ pin assertion, reducing standby current to 120 µA while disabling all I/O except ZZ.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory size	2 Mbit (128 K × 16), configurable as 256 K × 8 using UB/LB byte enables
Access time	60 ns (typ), enabling SRAM-like timing in existing memory bus designs
Endurance	10¹⁴ read/write cycles-supports daily logging for >270 years at 1000 writes/day
Data retention	151 years at +85 °C; no refresh or backup power required
Supply voltage	2.0 V to 3.6 V-compatible with 2.5 V and 3.3 V industrial logic rails
Operating temperature	–40 °C to +85 °C-qualified for industrial embedded environments
Active current	7 mA (typ) at 3.3 V/60 MHz-reduces thermal load in dense PCB layouts

Pinout & Package

FM28V202A-TGTR is housed in a 44-pin thin small outline package (TSOP-II, 400-mil width), surface-mount compatible with standard reflow profiles and requiring no through-hole mounting or mechanical retention.

Pin/Terminal	Circuit Role	Design Meaning
A0–A16	Address inputs	17-bit address bus latched on CE fall; A1–A0 enable 4-column page-mode access per row
DQ0–DQ15	Data I/O	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; deassertion starts pre-charge
OE	Output enable	Controls DQ bus drive; HI-Z when HIGH-eliminates bus contention transients
UB / LB	Byte select	Enable upper/lower 8-bit data lanes independently; allow byte-wide access or 256K×8 configuration
ZZ	Sleep control	LOW enters ultra-low-power sleep (120 µA); must be HIGH for normal operation
VDD / VSS	Power / ground	Single 2.0–3.6 V supply; no separate V_PP or backup rail needed

Key Features

Feature	Design Value
NoDelay™ write architecture	Writes complete in same 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 hardware jumpers or fuses
SRAM pinout and timing compatibility	Direct drop-in replacement for 128 K × 16 SRAMs-no PCB or firmware changes needed
Monolithic nonvolatility	Eliminates battery, supercapacitor, and associated reliability risks-no rework or maintenance
Page-mode performance	30-ns cycle time for sequential column accesses within same row-doubles effective throughput vs random access

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-SPXC	Same F-RAM technology, but 2-Mbit (128 K × 16) in SOIC-44; lacks TSOP-II footprint and has higher 100-ns access time	Preferred for through-hole prototyping or legacy board reuse; not suitable for space-constrained SMT designs	Select when board layout requires SOIC package or when lower speed tolerance allows relaxed timing margins
AT25DF041A-SH-B	4-Mbit SPI serial flash with 85 MHz clock; requires protocol translation, no true SRAM interface or NoDelay writes	Requires MCU firmware changes, interrupt-driven writes, and wear-leveling-unsuitable for high-frequency burst logging	Choose only if system already uses SPI peripherals and write frequency is <100 Hz; not a functional substitute for parallel F-RAM

Compared with CY14B102QN-SPXC and AT25DF041A-SH-B, FM28V202A-TGTR uniquely delivers SRAM-equivalent parallel timing, monolithic nonvolatility, and 10¹⁴ endurance in a compact TSOP-II package-making it the only option for high-speed, high-reliability industrial data capture without architectural redesign.

FAQ

Is FM28V202A-TGTR a true SRAM drop-in replacement?

Yes. It uses an industry-standard 128 K × 16 parallel interface with identical pinout, 60-ns access time, and CE/WE/OE control logic. No timing adjustments, address decoding changes, or firmware modifications are required-only power supply and decoupling must match its 2.0–3.6 V range.

How does software write protection work without external pins?

Protection is implemented via a deterministic six-read/three-write command sequence issued over the standard address/data bus. Each of the eight 16 K × 16 sectors is controlled by one bit in a nonvolatile protection register, retained indefinitely without power or battery.

What happens during power loss while writing?

No data corruption occurs. Because F-RAM writes are inherently atomic and complete in a single bus cycle (NoDelay™), any write in progress at power loss is either fully committed or not started-unlike flash or EEPROM, which risk partial-page corruption or require complex recovery routines.

Can FM28V202A-TGTR operate at 2.0 V and still meet 60-ns access time?

No. The 60-ns access time is specified at VDD = 3.0 V to 3.6 V. At 2.0–2.7 V, access time increases to 90 ns (max), and cycle time extends to 120 ns. Designers must verify timing margins against their operating voltage and clock rate.
