Product details
Overview
SST39VF801C-70-4I-EKE from Microchip Technology is a 8 Mbit (512K × 16) CMOS Multi-Purpose Flash Plus memory IC with SuperFlash® technology, operating at 2.7–3.6 V, featuring 70 ns read access time, hardware block protection for bottom 8 KWord boot sector, and JEDEC-standard x16 parallel interface. It serves as nonvolatile program/data storage in embedded controllers, BIOS firmware modules, and industrial HMI systems.
For engineers reviewing the SST39VF801C-70-4I-EKE datasheet, SST39VF801C-70-4I-EKE pinout, SST39VF801C-70-4I-EKE application, or SST39VF801C-70-4I-EKE equivalent, key selection criteria include boot-block architecture (bottom-protect), TSOP-48 packaging, 100,000-cycle endurance, RY/BY# status signaling, and compatibility with standard microprocessor bus timing.
Technical Context
The SST39VF801C-70-4I-EKE implements a split-gate SuperFlash® cell architecture enabling fixed erase/program times independent of cycle count, eliminating software de-rating. Its command-set follows JEDEC-standard flash protocols including six-byte sector/block/chip-erase sequences and three-byte word-program initiation.
It supports dual status detection via DQ7 Data# Polling and DQ6 Toggle Bit, plus open-drain RY/BY# output requiring external 10 kΩ–100 kΩ pull-up. Hardware write protection is enabled by grounding WP# to lock the bottom 8 KWord boot block (00000H–01FFFH), while RST# provides hardware reset to Read mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16 organization), directly maps to 16-bit data bus without byte-lane splitting |
| Read Access Time | 70 ns - determines maximum sustained read throughput in legacy 16-bit microprocessor systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV800CTTC-70G | 8 Mbit (512K × 16), 70 ns, 2.7–3.6 V, top-boot configuration (0x7E000–0x7FFFF protected) | Protects top boot block instead of bottom; incompatible boot-sector address map for SST39VF801C-70-4I-EKE designs | Select only if redesigning boot code layout to reside in top sector and verifying WP# logic polarity match |
| EN29LV800AB-70TP | 8 Mbit (512K × 16), 70 ns, 2.7–3.6 V, bottom-boot but lacks RST# pin and CFI support | No hardware reset pin limits recovery from failed writes; absence of CFI complicates auto-detection in generic bootloader stacks | Acceptable for cost-sensitive, fixed-function systems where reset handling is software-managed and CFI is unused |
Compared with MX29LV800CTTC-70G and EN29LV800AB-70TP, the SST39VF801C-70-4I-EKE uniquely combines bottom-boot protection, integrated RST#, CFI compliance, and SuperFlash® fixed-timing - making it optimal for safety-critical or field-upgradeable embedded systems requiring guaranteed boot integrity and status visibility.

FAQ
What is the boot block configuration of the SST39VF801C-70-4I-EKE?
The SST39VF801C-70-4I-EKE features bottom-boot block protection covering the lowest 8 KWord (32 KB) address range 00000H–01FFFH. This is implemented via the WP# pin: when grounded, it prevents program/erase operations on that sector. The device ID 233BH (per Table 5) confirms this bottom-boot variant, distinguishing it from the top-boot SST39VF802C (ID 233AH). This configuration ensures safe storage of primary boot code.
Does the SST39VF801C-70-4I-EKE require an external VPP voltage for programming?
No, the SST39VF801C-70-4I-EKE does not require an external VPP voltage. Internal charge pump circuitry generates all necessary high-voltage programming signals from the single 2.7–3.6 V VDD supply. Table 9 confirms VPP min/max values as 0000H, indicating no VPP pin or external voltage requirement - simplifying board design and reducing BOM count.
How is write operation completion detected on the SST39VF801C-70-4I-EKE?
Write completion on the SST39VF801C-70-4I-EKE is detected using three complementary methods: (1) RY/BY# pin (open-drain, requires pull-up), (2) DQ7 Data# Polling (complement toggles until complete), and (3) DQ6 Toggle Bit (alternates until operation ends). All are valid after the rising edge of the fourth WE# pulse for word-program, or sixth for erase operations - enabling flexible host-side polling or interrupt-driven handling.
What package type is used for the SST39VF801C-70-4I-EKE?
The SST39VF801C-70-4I-EKE uses a 48-lead TSOP (Thin Small Outline Package) with standard Type I pinout (12 mm × 20 mm body size), as shown in Figure 2 of DS25041A. This surface-mount package supports conventional reflow soldering and is mechanically and electrically compatible with industry-standard 16-bit flash sockets used in industrial and telecom equipment.
Is the SST39VF801C-70-4I-EKE RoHS compliant?
Yes, the SST39VF801C-70-4I-EKE is RoHS compliant, as explicitly stated in the datasheet footer and Section "Packages Available". It meets EU Directive 2011/65/EU requirements for restriction of hazardous substances, including lead-free terminations and compliant molding compounds - verified through Microchip's material declarations and test reports.
