Product details

The TM4C1237H6PZIR runs an ARM Cortex-M4F core at 80 MHz, with a single-precision floating-point unit on die.

256 KB Flash + 32 KB RAM — sizing the firmware and data buffers

Program memory is 256 KB Flash, paired with 32 KB SRAM and a separate 2 KB EEPROM block.

Connectivity mix: USB OTG, CAN, and five serial protocols

The USB OTG lets the part act as a USB-to-CAN gateway or a data-logger host for a thumb drive. CAN is the industrial backbone here — the Tiva C family was designed with CAN in mind, so the message-object RAM and filtering are baked into the peripheral, not bit-banged.

Frequently asked questions

What is the TM4C1237H6PZIR's core speed?
