C8051F411-GM

The C8051F411-GM is Silicon Labs’ 8‑bit, 8051‑compatible microcontroller in the C8051F4x1 family. It combines an 8051 core with on‑chip Flash and RAM, plus a rich peripheral set in a compact, low‑power package. Typical peripherals include a 12‑bit ADC, DAC, multiple timers/PWM, UART/SPI/I2C, GPIO, watchdog, and power‑management features. The GM suffix denotes a RoHS‑compliant package/grade. The device supports in‑circuit programming/debugging via Silicon Labs tools (Simplicity Studio) and standard 8051 toolchains. Common applications are data acquisition, instrumentation, sensor conditioning, motor control, and compact embedded control. For exact memory size, clock specs, peripheral counts, and package options, consult the C8051F411 datasheet and user guide.

Equivalent products are other members of Silicon Labs’ C8051F41x family. Examples: C8051F410-GM, C8051F412-GM, C8051F413-GM (and other packaging variants like -GQ). They use the same 8051 core and peripherals; the differences are mainly flash/RAM sizes and packaging.
