Product details
Overview
SST39LF200A-45-4C-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 code/data storage in embedded microcontroller systems requiring field-upgradable firmware.
For engineers reviewing the SST39LF200A-45-4C-EKE datasheet, SST39LF200A-45-4C-EKE pinout, SST39LF200A-45-4C-EKE application, or SST39LF200A-45-4C-EKE equivalent, key selection considerations include its x16 asynchronous interface, JEDEC-standard flash command set, sector/block erase architecture, and TSOP-48 packaging compatible with legacy PCB layouts.
Technical Context
The SST39LF200A-45-4C-EKE implements a split-gate SuperFlash cell with thick-oxide tunneling injector for enhanced reliability and fixed erase/program timing independent of cycle count. It supports standard JEDEC x16 flash pinouts and command protocols including Software Data Protection (SDP) with three-byte unlock sequences for programming and six-byte sequences for erasure.
Operation modes include Read (CE# & OE# low), Word-Program (CE# low, WE# low, OE# high), Sector/Block/Chip-Erase (via command sequences), and Standby (CE# high). End-of-write detection uses DQ7 Data# Polling and DQ6 Toggle Bit, both valid after the fourth (program) or sixth (erase) WE# pulse rising edge.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV200CTTI-70G | 2 Mbit x16, 70 ns access, 2.7–3.6 V supply, 100K cycles, same TSOP-48 package | Larger 64 KB uniform blocks only (no 2 KB sectors); no CFI support | Select when block-level updates suffice and CFI-based auto-configuration is unnecessary |

FAQ
What is the maximum operating frequency supported by the SST39LF200A-45-4C-EKE?
The SST39LF200A-45-4C-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 in systems with zero wait-state timing. The device relies on CE#, OE#, and WE# control signals rather than a system clock, making it compatible with microcontrollers lacking dedicated flash interfaces.
Does the SST39LF200A-45-4C-EKE require an external VPP voltage for programming?
No, the SST39LF200A-45-4C-EKE 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 eliminates the need for additional voltage regulators or high-voltage generation circuitry on the PCB, simplifying design and reducing bill-of-materials cost.
How many erase sectors does the SST39LF200A-45-4C-EKE contain, and what is their size?
The SST39LF200A-45-4C-EKE contains 64 uniform erase sectors, each sized at 2 KWords (4 KB). This is confirmed by CFI Query Table 7 (address 2DH = 003FH → y+1 = 64 sectors) and 2FH = 0010H → z × 256B = 4 KB/sector. Sector erase enables targeted firmware updates without disturbing adjacent code or data regions.
Is the SST39LF200A-45-4C-EKE pin-compatible with the SST39VF200A series?
Yes, the SST39LF200A-45-4C-EKE is pin-compatible with the SST39VF200A series in the same package (e.g., TSOP-48), sharing identical pinout, command set, and x16 interface. However, the VF variant operates at 2.7–3.6 V and has 70 ns read access, while the LF variant requires 3.0–3.6 V and delivers 55 ns access-requiring voltage rail verification before substitution.
What mechanisms protect the SST39LF200A-45-4C-EKE against inadvertent writes during power transitions?
The SST39LF200A-45-4C-EKE employs three hardware protections: (1) noise/glitch filtering rejecting WE#/CE# pulses <5 ns, (2) VDD power-up/down detection inhibiting writes below 1.5 V, and (3) Write Inhibit Mode activated by OE# low, CE# high, or WE# high. These ensure safe operation during brown-out, reset, or hot-plug events without external supervision circuitry.
