World's first serial EEPROM supporting ACR SIG
Microchip has announced the world's first serial EEPROM supporting the Advanced Communications Riser Special Interest Group (ACR SIG) specification.
Easy interfacing to faster microcontrollers
Microchip has added two new devices to its PIC16C92X family of 8bit one-time-programmable microcontrollers with integrated liquid-crystal display controller.
This new ANSI-compliant compiler also includes unique language extensions to use DSP functionality.
The free MPLAB C30 Student Edition offers the same functionality for 60 days, after which it maintains full source-code compatibility and device support, with no memory limitations, but without additional code optimisation.
This is a great tool for students, colleges and universities, and also for design engineers interested in learning about Microchip's 16bit devices and language tools.

Flash microcontrollers run up to 10MIPS
Microchip's new PIC18F010 and PIC18F020 Flash microcontrollers offer an industry-leading performance of 10MIPS, 4Kbyte of program memory, 256byte of user RAM and 64byte of EEPROM.
Micropower op amp shrinks into SOT-23 package
Microchip's new 2.5 V micropower operational amplifier is available in a tiny SOT-23 package.
Microchip developed the new compiler alongside the PIC24 and dsPIC33 controller families to ensure optimal C code efficiency, which can be up to 85% smaller than competitive 16bit architectures.
MPLAB C30 is tightly integrated into the free MPLAB Integrated Development Environment for writing code, building projects and testing using Microchip's software simulator or the MPLAB ICD 2 In-Circuit Debugger.
Final optimised code can be programmed into devices either with the cost-effective MPLAB ICD 2 or the MPLAB PM3 production device programmer, using the same MPLAB user interface.
MPLAB IDE is unique in offering a free, fully integrated environment for 8 and 16bit microcontrollers, and 16bit digital signal controllers - covering devices from 6 to 100 pins.
The compiler is distributed with a complete ANSI C standard library including functions for string manipulation, dynamic memory allocation, data conversion, timekeeping and trigonometric, exponential and hyperbolic mathematics.
The MPLAB C30 suite also includes I/O functions for file handling, along with complete low-level source code for those functions.
The MPLAB C30 compiler supports inline assembly code in C source files, as well as separately assembled MPLAB ASM30 assembly language modules.
This allows highly optimised interrupt routines, precision peripheral control and efficient, high-speed assembly language functions.
Other tools in the MPLAB C30 suite include the MPLAB Link30 linker and a librarian, and several utility modules for the MPLAB ASM30 assembler.
The dsPIC digital signal controllers are supported by a host of C-callable libraries, including: mathematics, peripheral and DSP algorithm libraries, as well as a soft modem library, acoustic echo cancellation library, noise suppression library, speech recognition library, speech encoding/decoding library and asymmetric/symmetric key embedded encryption library.
Most of these libraries are available for free download, or for a $5.00 evaluation fee, from the Microchip website.
MPLAB C30 Version 2.0 is available now at a cost of $895.
Owners of previous MPLAB C30 Versions can download a free upgrade and user's guide from Microchip's website.
The Student Edition (MPLAB C30 SE) can also be downloaded for free.
