Pessoal,
Estou saindo dos ARMs e tenho uns aqui preferência pra troca - aceito propostas, tenho os seguintes modelos:
01 LPC2478
01 LPC1766
01 LPC2138 já soldado na placa adaptadora para pinagem DIP
os 2 primeiros não foram usados ainda, o 2138 usado e em funcioando Ok

* 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 or HVQFN 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.
* In-System Programming/In-Application Programming (ISP/IAP) via on-chip bootloader software. Single flash sector or full chip erase in 400 ms and programming of 256 B in 1 ms.
* EmbeddedICE RT and Embedded Trace interfaces offer real-time debugging with the on-chip RealMonitor software and high-speed tracing of instruction execution.
* One (LPC2131/32) or two (LPC2134/36/38) 8-channel 10-bit ADCs provide a total of up to 16 analog inputs, with conversion times as low as 2.44 us per channel.
* Single 10-bit DAC provides variable analog output (LPC2132/34/36/38).
* Two 32-bit timers/external event counters (with four capture and four compare channels each), PWM unit (six outputs) and watchdog.
* Low power Real-time clock with independent power and dedicated 32 kHz clock input.
* Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 kbit/s), SPI and SSP with buffering and variable data length capabilities.
* Vectored interrupt controller with configurable priorities and vector addresses.
* Up to forty-seven 5 V tolerant general purpose I/O pins in tiny LQFP64 or HVQFN package.
* Up to nine edge or level sensitive external interrupt pins available.
* 60 MHz maximum CPU clock available from programmable on-chip PLL with settling time of 100 us.
* On-chip integrated oscillator operates with external crystal in range of 1 MHz to 30 MHz and with external oscillator up to 50 MHz.
* Power saving modes include Idle and Power-down.
* Individual enable/disable of peripheral functions as well as peripheral clock scaling down for additional power optimization.
* Processor wake-up from Power-down mode via external interrupt or BOD.
* Single power supply chip with POR and BOD circuits:
o CPU operating voltage range of 3.0 V to 3.6 V (3.3 V +- 10 pct) with 5 V tolerant I/O pads.
Valeu, abraço
