8- vs. 16-bit vs. Cortex -M0 Current Comparison
12
Cortex -M0 Has Lower Power Consumption
Cortex-M0 runs at a much slower clock frequency for the same required performance
Cortex-M0 can sleep most of the time, or spare the resource for handling additional tasks

Instruction Size for Various Processors
8051 PIC18 PIC24 MSP430/MSP430XLeading to superior code density:
In Cortex-M0 all instructions (except BL) are 16-bit wide instructions
Over 64K of address space, 8- and 16- processors have to introduce paging leading to extra overhead in code

Important Features for 8/16 -bit MCU Customers
Timers with PWM Generation For each timer, up to four match registers can be configured as PWM, each timer supports up to three match outputs as single edge controlled PWM outputs;
Dynamic System Clock Switching Change frequency on the fly depending on processing demand. The LPC1100 current consumption at 50 MHz is specified at 7mA. This can be reduced to a little over 130uA when running at 1 MHz on the low-power internal oscillator;
Clock Output Clock output with divider can reflect the system oscillator clock, IRC clock, CPU clock, and the Watchdog clock. Output can source downstream devices such as other microcontrollers, CPLD or FPGA;
Interrupt via Any GPIO Any GPIO pins can be used as Edge and Level Sensitive interrupt sources;
Programmable Pull Up/Down/Open Drain Internal pull-up/pull-down resistor, pseudo open drain or bus keeper function;
Enhanced GPIO Pin Manipulation Capable of simultaneously reading Bit/Byte/Word or toggling up to 22 I/Os per instruction
