Product details

Overview

ST7F264-IND/USB from STMicroelectronics is an in-circuit debugging and programming kit for ST7 Flash microcontrollers, specifically supporting the ST72F264 (SDIP32) MCU. It provides USB host interface, 10-pin ICC connection to target boards, real-time execution monitoring, unlimited instruction breakpoints, and data-access advanced breakpoints.

For engineers reviewing the ST7F264-IND/USB datasheet, ST7F264-IND/USB pinout, ST7F264-IND/USB application, or ST7F264-IND/USB equivalent, key selection criteria include USB-based host connectivity, SDIP32-targeted evaluation board inclusion, ICC protocol compliance, and STVD7 IDE integration for ST7 family development.

Technical Context

The ST7F264-IND/USB implements ST's proprietary In-Circuit Communication (ICC) protocol over a 10-pin physical interface, enabling bidirectional debug session control and Flash memory programming. It supports symbolic source-level debugging via STVD7 and leverages the on-chip debug module of the ST72F264 MCU for real-time register/peripheral watch and instruction stepping.

Hardware includes an ICC interface board with USB 2.0 full-speed interface (12 Mbps), onboard voltage level translation for 3.3 V/5 V target compatibility, and a dedicated evaluation board populated with ST7F2649 in SDIP32 package. Debug features are constrained by target MCU capabilities - advanced breakpoints require on-chip debug module presence.

Key Specifications

Parameter	Value and Actual Design Meaning
Host Interface	USB 2.0 full-speed (12 Mbps); eliminates need for parallel port or serial adapter on modern PCs.
Target Interface	10-pin ICC connector; standardized pinout per ST7 specification for reliable debug session initialization.
Included Evaluation Board	ST7F2649 in SDIP32 package; enables immediate hardware validation without external board design.
Debug Capability	Unlimited instruction breakpoints + data-access breakpoints (address range, access type); enables precise fault isolation in Flash-resident code.
Programming Support	Blank check, erase, read, verify for Flash and option bytes; ensures reliable firmware update and security configuration.
IDE Integration	Includes inDART edition of STVD7; provides unified environment for editing, compiling, downloading, and debugging ST7 assembly/C projects.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, power ICs, sensors, and analog/mixed-signal devices for industrial, automotive, and consumer applications.

This kit belongs to ST's ST7 ecosystem support tools product line, developed to accelerate firmware development and reduce time-to-debug for legacy ST7 Flash MCUs used in cost-sensitive, low-power embedded systems.

FAQ

Is ST7F264-IND/USB compatible with ST72F262 or ST72F265?

Yes - ST7F264-IND/USB supports all ST72F26x variants including ST72F262 and ST72F265, as confirmed by ST's Device Summary Table and ICC protocol compatibility across the F26x subfamily. The included evaluation board uses ST7F2649, but firmware and debug sessions are portable across pin-compatible derivatives with identical memory map and debug module implementation.

Does ST7F264-IND/USB require external power for the target board?

No - the ST7F264-IND/USB interface board does not supply power to the target; it relies on the target board's own power source. Voltage level translation circuitry supports both 3.3 V and 5 V ST7 targets, but users must ensure stable local VDD and proper decoupling on the application board before initiating ICC communication.

Can ST7F264-IND/USB program option bytes and disable debug access?

Yes - the in-circuit programming functionality explicitly includes option byte read/verify/erase/write operations. This allows permanent disabling of the ICC interface by setting the appropriate security bits, as defined in the ST72F264 reference manual, ensuring production firmware protection after development.

What software is required beyond STVD7 to use this kit?

Only STVD7 (inDART edition) is required - no additional drivers or middleware. Windows XP/Vista/7 compatible USB drivers are bundled with the kit. No third-party JTAG adapters, OpenOCD configurations, or GCC toolchain modifications are needed; STVD7 handles compilation, download, and debug session management end-to-end for ST7 assembly and C projects.
