Product details

ARM Cortex-M0 at 45 MHz — what the core speed buys you

The LPC1224FBD64/121151: Runs an ARM Cortex-M0 core at 45 MHz. 55 I/O lines are available.

48 KB Flash, 4 KB RAM — fitting the firmware

48 KB Flash and 4 KB RAM. Internal oscillator trims BOM.

The LPC1224 integrates I²C, SPI, SSI, SSP, UART/USART, IrDA, and Microwire — covering most serial buses found on sensors, memory chips, and wireless modules. The 8-channel 10-bit ADC is adequate for reading potentiometers, thermistors, or current-sense resistors at low update rates.

Frequently asked questions

What is the closest pin-compatible alternative to LPC1224FBD64/121151?

Within the LPC1200 series, the LPC1224FBD64/121151 shares the same 64-LQFP footprint and pinout as other LPC122x variants with different Flash/RAM sizes — the LPC1225 and LPC1226 are density upgrades that drop in without a board spin, though the evidence does not list a specific order code as a validated second source.

Can LPC1224FBD64/121151 be programmed with an SWD debugger?

Yes, the ARM Cortex-M0 core supports Serial Wire Debug (SWD) for programming and debug, using the standard SWDIO and SWCLK pins available on the 64-LQFP package.

What is the LPC1224FBD64/121151 pinout and package drawing?

The LPC1224FBD64/121151 is supplied in a 64-LQFP package with a 10x10 mm body; the pinout follows the standard LPC122x 64-pin assignment, with 55 general-purpose I/O pins and dedicated SWD, serial, and analog pins. A full pinout diagram is in the NXP LPC122x datasheet.
