PRODUCT SHOWCASE Microchip’s first PIC32C microcontroller If your design has outgrown the capabilities of one of the 8- or 16-bit micros, the PIC32C family (siliconchip.com. au/link/ab78) delivers easy scalability, enhanced performance and larger memory options while still being part of the MPLAB development ecosystem. The first of the PIC32C families, the PIC32CM MC, combines the performance and energy efficiency of an Arm Cortex-M0+ based micro with an optimised architecture and powerful peripherals. These 5V micros are ideal for motor/industrial control, home appliances, and other 5V applications. Key features include: • CPU clock speed up to 48MHz. • Up to 128KB embedded flash memory and 16KB of SRAM. • Operating voltage of 2.7-5.5V, which ensures the best possible SNR and noise immunity, EMC, ESD and latch up. • Dual 12-bit simultaneous sampling ADCs. • Positional decoder for motor control. • Timer/counter for control peripheral provides dedicated timers for industrial and motor control. • Four serial communication modules that can be configured to act as a USART, UART, SPI, I2C, RS485 or LIN bus interface. • 12-channel direct memory access controller with CRC module. • Functional pin compatibility with current SAM C20 devices in 32and 48-pin packages.

Unit 32, 41 Rawson Street Epping 2121 NSW Tel: (02) 9868 6733 www.microchip.com New analog products from Maxim provide double the battery life The MAX41400 (https://bit.ly/ MAX41400 Product) instrumentation amplifier enhances sensor system accuracy by four times and extends battery life by 55% compared to the closest competitive offering. The MAX41400 provides low offset of 25µV, low noise and programmable gain with only 65µA current consumption. The MAX40108 (https://bit.ly/ MAX40108 Product) is the lowestvoltage precision opamp in its class, operating with supplies as low as 0.9V. The combination of low operational supply voltage, lower power consumption and 25.5µA quiescent current allows engineers to double sensor battery life. The MAX31343 (https://bit.ly/ MAX31343 Product) I2C RTC with integrated MEMS oscillator provides timekeeping accuracy of ±5ppm, substantially better than the closest competitor, plus robust protection afforded by a MEMS resonator. With its integrated resonator, the MAX31343 eliminates crystal me- chanical failures and enables the smallest WLP compared to any other competitor in the market. All these products are offered with multiple and small form factor package choices. Maxim Integrated 160 Rio Robles San Jose, CA 95134 USA www.maximintegrated.com New APEM Q25 & Q30 series LED indicators The Q25 and Q30 series LED indicators use a PCB with 6 SMT chips and built-in failsafe protection. A molded Fresnel lens scatters the LED light to give that all-round illumination making long distance and daylight viewing crystal clear. This series is suitable for material handling or off-highway vehicles where reverse and over voltage protection is required. It also comes with low heat generation suitable for mounting into heat sensitive plastics. The chamsiliconchip.com.au gered bezel is made from 316L marine grade stainless steel and is IP67 and IP69K front panel sealed.
