Ideal for low power (<100nA standby current) and connectivity applications that benefit from the availability of multiple serial ports (3xI2C, 3xSPI), 4xUARTS, and 23 independent timers. Large amounts of RAM (16kB) memory for buffering and large (up to 256kB) Enhanced Flash program memory make it ideal for embedded control and monitoring applications. PPS (peripheral pin select) aids in configuring the most efficient pin configuration of available I/O, and CTMU provides touch support for up to 64 individual buttons. Supports USB 2.0 for device, Host, and OTG with a complete and free software stack that includes a thumb drive application stack. Available in 64, 80, and 100 pin packages. <br><a href=”http://www.microchip.com/usb”>USB Application Design Center</a> <object width=”425″ height=”344″><param name=”movie” value=”http://www.youtube.com/v/ljF4KQ2mfD0&hl=en&fs=1″></param><param name=”allowFullScreen” value=”true”></param><param name=”allowscriptaccess” value=”always”></param><embed src=”http://www.youtube.com/v/ljF4KQ2mfD0&hl=en&fs=1″ type=”application/x-shockwave-flash” allowscriptaccess=”always” allowfullscreen=”true” width=”425″ height=”344″></embed></object> â€¢CPU –Up to 16 MIPS performance –16 x 16 Hardware Multiply, Single Cycle Execution –12-bit x 16-bit Hardware Divider –C Compiler Optimized Instruction Set â€¢nanoWatt Power Managed Modes –Run, Idle and Sleep modes –Multiple, Switchable Clock Modes for Optimum Performance and Power Management –Run mode: 1 mA/MIPS, 2.0V Typical –Sleep mode Current Down to 100 nA Typical –Standby Current with 32 kHz Oscillator:2.5 uA,2.0V typical â€¢Flash Program Memory –Self-Reprogrammable under Software Control –10,000 erase/write cycles –20 year data retention –EEprom emulation capable â€¢System –Internal oscillator support – 31 kHz to 8 MHz, up to 32 MHz with 4X PLL –On-chip LDO Voltage Regulator –JTAG Boundary Scan and Flash Memory Program Support –Fail-Safe Clock Monitor â€“ allows safe shutdown if clock fails –Watchdog Timer with separate RC oscillator â€¢Analog Features –10-bit ADC, 16 channels, 500k samples per second –Three Analog comparators â€¢Universal Serial Bus Features –USB v2.0 On-the-Go compliant –Dual role capable, can act as either Host or Device –Low speed(1.5Mb/s) and full speed(12 Mb/s) operation in host mode –Full speed USB operaton in Device mode –Supports 32 endpoints –On-chip USB transceiver â€¢Peripherals –CTMU supports Capacitive Touch applications –Perpheral Pin Select allows I/O remapping of many peripherals in real time –4xUART Modules with LIN and IrDA support, 4 Deep FIFO –3xSPI â„¢ Modules with 8 Deep FIFO –3xI2Câ„¢ Modules with Master and Slave Modes –Five 16-bit Timer Modules –Up to 9 Input Capture and 5 Output Compare/PWM with dedicated time base –Hardware RTCC, Real-Time Clock Calendar with Alarms –PMP, Parallel Master Port, with 16 Address Lines, and 8/16-bit Data

With the righ concept people can save a huge amount of money. Anyhow, there are still people on this nice plant that ask for the price of 100K GSM modules, without to have a hardware, software, marketing or sales concept. The opposite are people that emailing me or calling me and ask what I have to charge per day consulting. I also like business friends, that just place sample orders without to ask for bulk prices, because they are sure to get the best price.

I love people that do not talk to much and place trial orders. Nobody shall reinvent the wheel. I am glad to share my long term M2M experience with my customers. Last but not least everybody can reach me easy by email to harald.naumann (at) gsm-modem.de or by using the form and ask for a concept, development up to mass production. A one stop buying including dedicated support.
