NXP is giving away LPCXPresso boards to people who submit a video of themselves destroying an 8 or 16 bit micro. I'm not sure which board they're giving away or what the qualifications are for being eligible (the submission ominously requires a "Business" email address) but it's worth a try I suppose.
The Cortex M0 is positioned as an upgrade for existing 8 or 16 bit applications. Color me jaded, but the M0 specs are significantly more impressive than the typical 8/16 bit micro. The low-end LPC111x series tout the following features (datasheet):
- System:
- ARM Cortex-M0 processor, running at frequencies of up to 50 MHz.
- ARM Cortex-M0 built-in Nested Vectored Interrupt Controller (NVIC).
- Serial Wire Debug.
- System tick timer.
- Memory:
- 32 kB (LPC1114), 24 kB (LPC1113), 16 kB (LPC1112), or 8 kB (LPC1111) on-chip flash programming memory.
- 8 kB, 4 kB, or 2 kB SRAM
- In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software.
- Digital peripherals:
- Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors.
- GPIO pins can be used as edge and level sensitive interrupt sources.
- High-current output driver (20 mA) on one pin.
- High-current sink drivers (20 mA) on two I2C-bus pins in Fast-mode Plus.
- Four general purpose counter/timers with a total of four capture inputs and 13 match outputs.
- Programmable WatchDog Timer (WDT).
- Analog peripherals:
- 10-bit ADC with input multiplexing among 8 pins.
- Serial interfaces:
- UART with fractional baud rate generation, internal FIFO, and RS-485 support.
- Two SPI controllers with SSP features and with FIFO and multi-protocol capabilities (second SPI on LQFP48 and PLCC44 packages only).
- I2C-bus interface supporting full I2C-bus specification and Fast-mode Plus with a data rate of 1 Mbit/s with multiple address recognition and monitor mode.
- Clock generation:
- 12 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as a system clock.
- Crystal oscillator with an operating range of 1 MHz to 25 MHz.
- Programmable watchdog oscillator with a frequency range of 7.8 kHz to 1.8 MHz.
- PLL allows CPU operation up to the maximum CPU rate without the need for a high-frequency crystal. May be run from the system oscillator or the internal RC oscillator.
- Clock output function with divider that can reflect the system oscillator clock, IRC clock, CPU clock, and the Watchdog clock.
- Power control:
- Integrated PMU (Power Management Unit) to minimize power consumption during Sleep, Deep-sleep, and Deep power-down modes.
- Power profiles residing in boot ROM allowing to optimize performance and minimize power consumption for any given application through one simple function call. (LPC1100L series, on LPC111x/102/202/302 only.)
- Three reduced power modes: Sleep, Deep-sleep, and Deep power-down.
- Processor wake-up from Deep-sleep mode via a dedicated start logic using up to 13 of the functional pins.
- Power-On Reset (POR).
- Brownout detect with four separate thresholds for interrupt and forced reset.
- Unique device serial number for identification.
- Single power supply (1.8 V to 3.6 V).
- Available as 48-pin LQFP package, 33-pin HVQFN package, and 44-pin PLCC package.
That pretty much eclipses any 8/16 bit micro I've ever used. The LPC1111 is priced as low as $2.02 for one piece at Digi-Key. That's easily within the realm of hobbyist dollars! (The QFN packaging, though, could be a roadblock to many. You can get an LPC1100L in 48-LQFP for $2.80)
I think I'll head outside and take a few video clips of semiconductor destruction today.
