The NXP microcontroller family LPC214x
uses a high-performance 32-bit ARM7
core that operates at up to 60 MHz.
Each device has up to 512 KB of on-chip
Flash and up to 40 KB of on-chip SRAM
memory.
In-System Programming (ISP) and In-
Application Programming (IAP) software
minimize programming time – each 256-
byte line takes only 1 ms to program,

C-bus interfaces, and Fast I/O.
60-MHz, 32-bit
microcontroller with
ARM7TDMI-S
LPC214x
and a single-sector or full-chip erase
takes only 400 ms.
A 128-bit-wide memory interface and
a patented memory accelerator enable
32-bit code execution from Flash with
zero wait-states. For applications where
code size is critical, an alternative 16-bit
Thumb mode reduces code by more
than 30% with minimal performance
penalties.
Each microcontroller in the family
includes a USB 2.0 full-speed (12 Mbps)
device that supports 32 endpoints with
2 KB of endpoint RAM. In the LPC2146
and the LPC2148, up to 8 KB of the RAM
can be used by the USB DMA. In all
the devices, the USB function supports
Control, Interrupt, Bulk, and Isochronous
data-transfer modes. Designers can
