PRODUCT SHOWCASE New dsPIC33CH512MP Dual-Core, High Memory, Dual CAN-FD DSC The new dsPIC33CH512MP508 dual-core Digital Signal Controllers (DSC) from Microchip build on the previously released Microchip dsPIC33CH128MP508. The dual-core DSCs enable designers to isolate time-critical and safety-critical functions from system functions and communication routines. This family is optimised for highperformance embedded, digital power, motor control and safety critical applications running sophisticated algorithms. Applications include wireless power, server power supplies, drones and automotive sensors. What’s new in dsPIC33CH512MP508? • • • • • Extends flash size from 128 to 512KB in the dual core dsPIC33CH device family 512KB flash on Master core for AUTOSAR, complex application, communication stacks; 72KB PRAM (Program RAM) on Slave core for complex control algorithms Dual cores and advanced peripherals make systems robust and functionally safe Dual CAN-FD for robust communication Unprecedented peripheral integration in 6x6 package for BoM cost saving Electronex Expo returns to Sydney in 2020 • Features for Functional Safety: ECC Memory, MBIST, DMT, Dual WWDT and more • ICSP Write Inhibit (OTP) for secure boot loading together with CryptoAuthentication devices to target secure applications • Automotive AEC Q100 Grade 1 qualified, -40°C to +125°C Development tools include: dsPIC33CH Curiosity Development Board (DM300028-2) dsPIC33CH512MP508 Motor Control Plug-In Module (PIM) (MA330046) dsPIC33CH512MP508 General Purpose Plug-In Module (PIM) (MA330045) Contact: Microchip Technology Inc Unit 32, 41 Rawson St Epping NSW 2121 Tel: (02) 9868 6733 Website: www.microchip.com JST’s “Wet Process” Semiconductor Cleaning Equipment Automated wet-process cleaning equipment is suitable for chips, wafers, semiconductors and other electronic devices including lasers. The more complex the equipment, the greater the need for advanced, adaptable cleaning options. JST’s 300 CLV Cleaner and Stripping Tool offers a dry-to-dry process. Once product is placed in the dry tank, it can process through either single or multiple chemical processes, rinse and dry according to a pre-programmed recipe without operator intervention or mechanical moving parts to maintain.

It will be held at Rosehill Gardens from 9 – 10 September 2020. The move to the MCEC in Melbourne was an outstanding success with more than a 12% increase in attendance and a record number of exhibitors participating in the 2019 event. In a further endorsement for the growth of the electronics sector and the success of the event, 53% of visitors had not attended Electronex previously and over 90% were engineers, managers or involved in production or purchasing. Electronex was first held in 2010 and has grown to become the preeminent trade event for companies that utilise electronics in manufacturing, assembly or servicing. The SMCBA Surface Mount Conference is also held concurrently with the Expo. Free seminars are also held on the expo floor and cover a range of hot industry topics to complement the conference workshops. The Sydney Expo is now open for bookings and around 60% of the space had already been booked by late December last year. Australia’s electronics magazine February 2020  83
