Product details
Overview
SST39SF010A-55-4C-WHE-T from Microchip Technology is a 1 Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with 55 ns read access time, single 4.5–5.5 V supply operation, and uniform 4 KByte sector-erase architecture. It implements SuperFlash split-gate technology for high reliability in embedded firmware storage applications requiring field-upgradable code or configuration data.
For engineers reviewing the SST39SF010A-55-4C-WHE-T datasheet, SST39SF010A-55-4C-WHE-T pinout, SST39SF010A-55-4C-WHE-T application, or SST39SF010A-55-4C-WHE-T equivalent, this page delivers verified technical context, JEDEC-compliant x8 interface timing, sector-level erase control, hardware/software data protection, and RoHS-compliant 32-lead PLCC packaging details essential for industrial controller, BIOS, and legacy system design.
Technical Context
The SST39SF010A-55-4C-WHE-T uses SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed 18 ms sector-erase and 70 ms chip-erase times independent of program/erase cycle count. Its command-set architecture conforms to JEDEC standard x8 flash pinouts and supports software data protection via three-byte (program) and six-byte (erase) sequences.
It operates in commercial temperature range (0°C to +70°C), requires no external VPP generation, and features TTL-compatible I/O with tri-state outputs controlled by CE# and OE#. End-of-write detection is implemented via Data# Polling (DQ7) and Toggle Bit (DQ6), both valid after the fourth WE#/CE# pulse during byte-program operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8), directly maps to 128 KB of nonvolatile storage for boot code or parameter tables |
| Read Access Time | 55 ns - enables direct execution from flash (XIP) in 14 MHz microcontroller systems without wait states |
| Supply Voltage | 4.5–5.5 V - compatible with legacy 5 V logic rails and eliminates need for dedicated programming voltage |
| Endurance | 100,000 program/erase cycles - supports frequent firmware updates in field-deployed equipment |
| Data Retention | Greater than 100 years - ensures long-term integrity of stored calibration data or security keys |
| Sector Size | Uniform 4 KByte sectors - allows granular firmware patching without erasing full device contents |
| Active Current | 10 mA typical at 14 MHz - reduces thermal load in space-constrained industrial modules |
Pinout & Package
Package: 32-lead Plastic Leaded Chip Carrier (PLCC), RoHS compliant, body size 13.97 mm × 13.97 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K × 8 addressing; A16 is most significant address bit for SST39SF010A |
| DQ0–DQ7 | Data Input/Output | 8-bit bidirectional data bus; outputs enter high-impedance state when CE# or OE# is high |
| CE# | Chip Enable | Active-low chip select; device enters standby mode (30 µA) when high |
| OE# | Output Enable | Active-low output gate; controls data bus visibility independently of CE# for multiplexed bus sharing |
| WE# | Write Enable | Active-low write control; initiates byte-program, sector-erase, or chip-erase commands on rising edge |
| VDD | Power Supply | 4.5–5.5 V main supply; internal charge pump generates programming voltage - no external VPP required |
| VSS | Ground | Reference ground for all I/O and core logic; decoupling capacitor placement critical for noise immunity |
| NC | No Connection | Pins 12 and 31 are unconnected; must remain floating per datasheet Figure 2 |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell structure provides fixed erase/program times unaffected by accumulated wear, eliminating system-level de-rating |
| Hardware Data Protection | Glitch filtering (<5 ns pulses ignored), VDD power-up/down detection (<2.5 V inhibits writes), and write-inhibit mode prevent corruption during brown-out |
| Software Data Protection | JEDEC-standard three-byte (program) and six-byte (erase) command sequences permanently enabled at shipment |
| End-of-Write Detection | Dual status methods - Data# Polling (DQ7 toggles to true data) and Toggle Bit (DQ6 alternates) - enable efficient polling without timer overhead |
| JEDEC Pinout Compliance | Standard x8 parallel flash pin assignment enables drop-in replacement for other JEDEC-compliant 1 Mbit devices in existing PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM29LV010B-55EC | 55 ns access, 1 Mbit, 3.0 V core (3.0–3.6 V), but requires 12 V VPP for programming | Not suitable for 5 V-only systems; incompatible voltage domain necessitates level-shifting or dual-supply design | Select only if migrating to 3 V logic infrastructure and external VPP generation is acceptable |
| MX29LV160ETTI-55G | 16 Mbit density, 55 ns, 3.0 V supply, top/bottom boot-block architecture instead of uniform 4 KByte sectors | Boot-block layout complicates partial firmware updates; larger density increases cost and layout footprint unnecessarily | Choose only when higher capacity and 3 V operation are mandatory; not a functional substitute for SST39SF010A-55-4C-WHE-T's sector-erase model |
Compared with AM29LV010B-55EC and MX29LV160ETTI-55G, the SST39SF010A-55-4C-WHE-T uniquely combines 5 V single-supply operation, uniform 4 KByte sector erase, and JEDEC x8 pinout-enabling direct replacement in legacy 5 V embedded systems without voltage translation or firmware rearchitecture.

FAQ
What is the operating temperature range for the SST39SF010A-55-4C-WHE-T?
The SST39SF010A-55-4C-WHE-T is rated for commercial temperature operation from 0°C to +70°C. This range is explicitly defined in Table 5 of the official datasheet (DS20005022C) and applies to all electrical specifications including 55 ns read access time and 100,000-cycle endurance. Industrial-grade variants exist but are distinct part numbers.
Does the SST39SF010A-55-4C-WHE-T require an external VPP voltage for programming?
No, the SST39SF010A-55-4C-WHE-T does not require an external VPP voltage. Its internal charge pump generates the necessary high voltage for programming and erasing using only the 4.5–5.5 V VDD supply. This is confirmed in the "Features" section and "Device Operation" chapter of DS20005022C, which states "Automatic Write Timing – Internal VPP Generation".
How many address lines does the SST39SF010A-55-4C-WHE-T use?
The SST39SF010A-55-4C-WHE-T uses 17 address lines: A0 through A16. This is required to address its full 128K × 8 organization (217 = 131,072 bytes). The datasheet confirms A16 is the most significant address bit for the SST39SF010A family in Table 1 and Figures 2–4.
What package type is used for the SST39SF010A-55-4C-WHE-T?
The SST39SF010A-55-4C-WHE-T is packaged in a 32-lead Plastic Leaded Chip Carrier (PLCC). The "WHE-T" suffix denotes this RoHS-compliant PLCC variant, consistent with Microchip's ordering nomenclature and confirmed in the "Packages Available" section of DS20005022C.
Is the SST39SF010A-55-4C-WHE-T pin-compatible with other densities in the SST39SFxxxA family?
Yes, the SST39SF010A-55-4C-WHE-T shares identical pinout and command set with SST39SF020A and SST39SF040 in 32-lead PLCC packages. All three comply with JEDEC standard x8 flash pinouts, though address line significance differs (A16 for SST39SF010A, A17 for SST39SF020A, A18 for SST39SF040), requiring correct address decoding in system design.
