microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combine the microcontroller with 32 kB, 64 kB, 128 kB, 256 kB and 512 kB of embedded high-speed flash memory.Beijing Shouxi Zhixin offers the LPC2131/32/34/36/38 chip decryption
2.1 Enhancements brought by LPC213x/01 devices
Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original LPC213x. They also allow for a port pin to be read at any time regardless of its function.
Dedicated result registers for ADC(s) reduce interrupt overhead.
UART0/1 include fractional baud rate generator, auto-bauding capabilities and handshake flow-control fully implemented in hardware.
Additional BOD control enables further reduction of power consumption.
2.2 Key features common for LPC213x and LPC213x/01
16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 or HVQFN64 package.
8/16/32 kB of on-chip static RAM and 32/64/128/256/512 kB of on-chip flash program memory. 128-bit wide interface/accelerator enables high-speed 60 MHz operation.
