This means the firmware is factory-programmed or burned in a UV eraser/programmer cycle; there is no in-circuit reprogramming. It ships in a Bulk package, typical for devices destined for socketed programming or panel-mount prototyping. ## UVPROM memory — plan for factory-programmed firmware Because the HD6477042AFI28V uses UVPROM rather than Flash or EEPROM, field updates are not possible. The firmware must be finalized and burned before assembly — either at Hitachi (if factory-programming was ordered) or via an external UV EPROM programmer. For a BOM line, this locks the firmware revision at the time of the last-time buy; any bug fix requires a new device with corrected code. Read the SH7000 reference manual for the programming algorithm and verify your toolchain supports UVPROM devices. ## Lifecycle and sourcing — EOL phase, quoted to order The HD6477042AFI28V has an EOL hot lifecycle stage, meaning Hitachi discontinued production. ## Not a drop-in for HD6417751RBP200 The HD6417751RBP200 uses a SuperH SH-4 core at 200 MHz with 1.35 V supply and ROMless memory. The HD6477042AFI28V uses the SH7000 core with UVPROM.","metaTitle":"Hitachi HD6477042AFI28V 32-bit UVPROM MCU, SH7000 CPU","metaDescription":"Hitachi HD6477042AFI28V 32-bit UVPROM MCU with SH7000 CPU core.
