- C3520: This likely refers to a specific hardware target, possibly a PCB (Printed Circuit Board) revision or a device codename. In industrial contexts, "C35" series boards often contain ST7 or early STM8 microcontrollers used in automotive sensors, industrial controllers, or legacy consumer electronics.
- Flash Loader 7.5: This is the version identifier. Flash Loaders are bootloader utilities. Version 7.5 sits in the late-era ST7 Flash Loader family, offering stability for parallel and DFU (Device Firmware Update) modes.
- 4 CSC: "CSC" can stand for "Chip Select Configuration" or "Customer Specific Code." The "4" might denote a specific hardware interface revision or a particular communication channel (e.g., SPI channel 4 or CAN bus mapping).
- V0.2: A minor revision or beta indicator. Version 0.2 suggests this was an iterative patch, possibly fixing timing issues or adding support for a specific flash memory geometry.
- Citrus 218l: "Citrus" is almost certainly an internal project codename. ST and its third-party tool partners often use fruit-based codenames for development boards. "218l" likely points to the ST7F218 or a derivative chip—an 8-bit MCU with 128KB of flash, used in high-reliability automotive ECUs in the early 2000s. The "l" might denote a low-voltage variant (3.3V instead of 5V).
