Product details
Overview
SST39LF200A-55-4C-EKE from Microchip Technology is a 2 Mbit (128K × 16) CMOS Multi-Purpose Flash memory IC using SuperFlash technology, operating at 3.0–3.6 V with 55 ns read access time, 100,000 program/erase cycles endurance, and >100 years data retention. It serves as nonvolatile program/data storage in embedded microcontroller systems requiring field-upgradable firmware.
For engineers reviewing the SST39LF200A-55-4C-EKE datasheet, SST39LF200A-55-4C-EKE pinout, SST39LF200A-55-4C-EKE application, or SST39LF200A-55-4C-EKE equivalent, key selection criteria include x16 asynchronous interface timing, JEDEC-standard flash command set compatibility, sector/block erase granularity, hardware/software write protection, and TSOP-48 package suitability for space-constrained PCB layouts.
Technical Context
The SST39LF200A-55-4C-EKE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed 14 µs word-program and 18 ms sector/block-erase times independent of cycle count. Its control logic supports standard JEDEC x16 flash command sequences including Software Data Protection (SDP) with three-byte unlock for programming and six-byte unlock for erasure.
It features dual status detection-Data# Polling (DQ7) and Toggle Bit (DQ6)-for end-of-write verification, and integrates noise/glitch protection, VDD power-up/down detection, and write-inhibit mode via CE#/OE#/WE# logic states to prevent inadvertent writes during power transitions.

FAQ
What is the maximum operating frequency supported by SST39LF200A-55-4C-EKE?
The SST39LF200A-55-4C-EKE does not operate at a clock frequency-it is an asynchronous parallel flash memory. Its 55 ns read access time corresponds to a maximum effective bus speed of approximately 14 MHz (1/55 ns ≈ 18.2 MHz, derated for setup/hold). System timing must comply with AC specifications in Table 10, including 5 ns input rise/fall times and 30 pF load capacitance.
Does SST39LF200A-55-4C-EKE require an external VPP voltage for programming?
No, the SST39LF200A-55-4C-EKE does not require an external VPP voltage. It generates the necessary high-voltage programming pulses internally using its 3.0–3.6 V VDD supply. This eliminates the need for external charge pumps or high-voltage regulators, simplifying board design and reducing component count compared to older flash technologies.
How many erase sectors does SST39LF200A-55-4C-EKE have, and what is their size?
The SST39LF200A-55-4C-EKE contains 64 uniform erase sectors, each 2 KWords (4 KB) in size. This is confirmed by Table 7, where sector information shows y = 63 (003FH), so y + 1 = 64 sectors, and z = 16 (0010H), meaning z × 256 B = 4 KB per sector. Sector erase enables granular firmware updates without disturbing unrelated code or data regions.
Is SST39LF200A-55-4C-EKE compatible with standard JEDEC x16 flash controllers?
Yes, the SST39LF200A-55-4C-EKE conforms fully to JEDEC standard pinouts and command sets for x16 parallel flash memories. It supports standard Read, Word-Program, Sector-Erase, Block-Erase, Chip-Erase, and Software ID commands-including the mandatory three-byte unlock sequence-ensuring seamless integration with existing JEDEC-compliant flash controllers and bootloaders.
What package type is used for SST39LF200A-55-4C-EKE, and are there footprint-compatible alternatives?
The SST39LF200A-55-4C-EKE uses a 48-lead TSOP (Thin Small Outline Package) measuring 12 mm × 20 mm. Microchip also offers pin-compatible 48-ball TFBGA and WFBGA variants (e.g., SST39LF200A-55-4C-B3E), allowing migration to smaller footprints without redesigning the core interface logic-though PCB layout and thermal management must be validated per package.
