Product details
Overview
SST39LF200A-45-4C-EKE-T 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 controllers and firmware update modules.
For engineers reviewing the SST39LF200A-45-4C-EKE-T datasheet, SST39LF200A-45-4C-EKE-T pinout, SST39LF200A-45-4C-EKE-T application, or SST39LF200A-45-4C-EKE-T equivalent, key selection criteria include x16 asynchronous interface timing, JEDEC-standard flash command set compatibility, sector/block erase architecture, TSOP-48 packaging, and single-supply 3.3 V operation for legacy industrial MCU designs.
Technical Context
The SST39LF200A-45-4C-EKE-T implements a split-gate SuperFlash cell with thick-oxide tunneling injector, enabling fixed 14 µs word-program and 18 ms sector/block-erase times independent of cycle count. It supports standard JEDEC x16 flash pinouts and command protocols including Software Data Protection (SDP) with three-byte unlock sequence for program and six-byte sequence for erase operations.
End-of-write detection uses DQ7 (Data# Polling) and DQ6 (Toggle Bit), both valid after the fourth WE# pulse for programming and sixth WE# pulse for erase. The device conforms to Common Flash Interface (CFI) v1.0 and supports Product Identification mode via software ID entry (0x5555/0xAA → 0x2AAA/0x55 → 0x5555/0x90) to return manufacturer ID 0x00BF and device ID 0x2789.

FAQ
What is the exact memory organization of the SST39LF200A-45-4C-EKE-T?
The SST39LF200A-45-4C-EKE-T is organized as 128K words × 16 bits, totaling 2 Mbit (256 KB) of storage. This x16 configuration interfaces directly with 16-bit microcontrollers and DSPs, and its address space spans A0–A16 (17 address lines), with A16 selecting the upper/lower half of the array. The device supports uniform 2 KWord sectors (64 total) and 32 KWord blocks (4 total), as confirmed in Tables 7 and 11 of DS25001A.
Does the SST39LF200A-45-4C-EKE-T require an external VPP voltage for programming?
No, the SST39LF200A-45-4C-EKE-T does not require an external VPP voltage. It performs all program and erase operations using only the 3.0–3.6 V VDD supply, thanks to on-chip charge pump circuitry. This is explicitly stated in the Features section and Table 6 of DS25001A, which lists VPP min/max as 0000H - confirming absence of a VPP pin and eliminating need for external high-voltage generation.
How is write completion detected on the SST39LF200A-45-4C-EKE-T?
Write completion on the SST39LF200A-45-4C-EKE-T is detected using two hardware-supported methods: Data# Polling (DQ7) and Toggle Bit (DQ6). After the fourth WE# pulse for programming or sixth WE# pulse for erase, DQ7 returns true data upon completion, while DQ6 stops toggling. Both mechanisms are fully implemented in silicon and require no additional timing margins - details are specified in Sections 7–8 and Figures 8–9 of DS25001A.
Is the SST39LF200A-45-4C-EKE-T compatible with JEDEC-standard flash controllers?
Yes, the SST39LF200A-45-4C-EKE-T conforms to JEDEC standard pinouts and command sets for x16 flash memories, as stated in the Features and Product Description sections of DS25001A. It supports standard commands including Word-Program, Sector-Erase, Block-Erase, Chip-Erase, and Software ID Entry using the documented 3- or 6-byte sequences - ensuring interoperability with off-the-shelf flash controllers and BIOS/firmware stacks.
What package type is used for the SST39LF200A-45-4C-EKE-T?
The SST39LF200A-45-4C-EKE-T uses a 48-lead TSOP (Thin Small Outline Package) measuring 12 mm × 20 mm, as confirmed in the Features section and Figure 2 of DS25001A. The "-EKE-T" suffix denotes this specific TSOP-48 RoHS-compliant, lead-free variant. Pin assignments match JEDEC-standard x16 flash layouts, with dedicated VDD, VSS, CE#, OE#, WE#, and A0–A16/DQ0–DQ15 signals.
