SAMA5D2 Based SiPs Combine ARM Cortex-A5 Processor With Up to 128MB DDR2

Atmel SAMA5D2 ARM Cortex-A5 processor was released about two years ago with extended temperature range and lower power consumption compared to previous SAMAD5 processors, with the new SoC still targeting industrial Internet of Things (IIoT), wearables and point of sale applications. In recent years, we’ve seen companies packing main components into systems-in-package (SiP) with products such as Octavo Systems OSD3358 and Espressif Systems ESP32-PICO-D4 with integrate an existing processor with memory, storage, and/or PMIC. Microchip (previously Atmel) has now done the same for their SAMA5D2 processors with SiPs combining the Cortex A5 SoC with DDR2 memory. Four SAMA5D2 SiPs have been launched: ATSAMA5D225C-D1M based on ATSAMA5D22C MPU with extra SD/SDIO, QSPI, FLEXCOMs (2x), I2S, and timers (2x) and: 128 Mb (16 MB) DDR2 DRAM 90 Peripheral I/Os 196 BGA Package Designed for RTOS/bare metal development ATSAMA5D27C-D5M based on ATSAMA5D27C MPU with: 512 Mb (64 MB) DDR2 DRAM 128 Peripheral I/Os […]

Microchip EERAM Combines SRAM and Backup EEPROM into a Single Chip

Most micro-controllers comes with both SRAM volatile memory, and flash or EEPROM for non-volatile (persistent) memory, but Texas Instruments – and other companies – have been selling MCUs with FRAM (Ferroelectric Random Access Memory) and standalone FRAM chip, a non-volatile memory that delivers performance and power efficiency similar to SRAM, and much better endurance that either flash or EEPROM. You don’t see FRAM in that many MCUs and solutions, because it’s more expensive than having SRAM + flash, but some applications requiring ultra low power consumption and non-volatile storage write capabilities may benefit from the technology. Those include data logging, sensor networks, and batteryless applications. Microchip has also it own technology with EERAM, a non-volatile SRAM memory that includes a “shadow” EEPROM used to automatically backup data on power down with a small external capacitor providing enough power to save SRAM to the EEPROM. Once power is recovered (Vdd > […]

Arduino MKRFOX1200 Board Combines Microchip SAM D21 MCU with Sigfox Module in MKRZero Form Factor

Arduino MKRFOX1200 is the first official Arduino board to feature LPWAN technology thanks to a Microchip ATA8520 Sigfox module combined with a Microchip SAMD21 ARM Cortex M0+ micro-controller, all that in the same form factor as MKRZero or MKR1000 boards. Arduino MKRFOX1200 specifications: MCU – Microchip SAMD21 ARM Cortex-M0+  MCU @ 48 MHz with 256KB flash, 32KB SRAM Connectivity – Microchip AT8520 Sigfox module operating @ 868 MHz with 2dB “GSM” antenna connected to u.FL connector 2x 14-pin headers for I/Os: 8x digital I/O 8x external interrupts (0, 1, 4, 5, 6, 7, 8, A1 -or 16-, A2 – or 17) 7x analog inputs (8/10/12-bit ADC) 1x analog out (10-bit DAC) 12x PWM pins ((0, 1, 2, 3, 4, 5, 6, 7, 8, 10, A3 – or 18 -, A4 -or 19) 1x UART, 1x SPI, 1x I2C 3.3V operating voltage DC Current per I/O Pin 7 mA USB – […]

Secure IoT Connectivity with NodeMCU ESP8266 Board, ATECC508A Crypto Chip, Mongoose OS, and AWS IoT

There are many examples of Internet of Things projects, but more often than not the implementation is not secure, either because the device is exposed to the Internet with minimum or no security (worst case), or a gateway (hopefully) provides secure connection to the Internet, but the communication between sensor nodes and the gateway in the local network is not secure, due to memory limitation of the nodes, for example it might be challenging to implement security on ESP8266. Mongoose OS is an open source operating system for the Internet of Things developed by Cesanta working on ESP32, ESP8266, STM32, and TI CC3200, and the developers have demonstrated a secure solution with Mongoose OS running on ESP8266 connecting over a TLS connection to AWS IoT (Amazon Web Service IoT) and using TLS credentials stored in Microchip ATECC508A CryptoAuthentication Device. The addition of ATECC508 chip either using “XplainedPro extension board for […]

Microchip Atmel ATtiny417/814/816/817 tinyAVR MCUs Include Core Independent Peripherals (CIPs)

Microchip’s latest Atmel tinyAVR MCUs combine Atmel 8-bit AVR core with CIPS (Core Independent Peripherals) normally found in the company’s PIC MCUs. Since Atmel’s purchase by Microchip, I believe this is the first time the company leverages features from both MCU families. The four new ATtiny MCUs come with 4 to 8 KB flash, and up to 24 pins: ATtiny417 – 8-bit Atmel AVR MCU with 4KB Flash, 256 bytes SRAM, 128 bytes EEPROM, 20MHz/20 MIPS, two 16-bit timer/counters, one 12-bit timer/counter, RTC, USART, SPI, Two-wire Interface (I2C), 10-bit ADC, 8-bit DAC, analog comparator, accurate internal oscillators and multiple calibrated voltage references, Custom Logic, 10-bytes unique ID, and 24 pins ATtiny814 – Same as above but with 8KB flash, 512 bytes SRAM, Peripheral Touch Controll (PTC), and 14 pins ATtiny816 – Same key features as ATtiny814 but with a 20-pin package with more I/Os ATtiny817 – Same key features as […]

Getting Started with MPLAB Xpress Board and Online IDE

Microchip launched MPLAB Xpress online IDE and board earlier this year, and as part of the launch they offered 2,000 free boards. I joined the program and received my board. The keyword for the board is “Xpress”, as you should be able to get started in mere minutes thanks to the operating system agnostic online IDE that works with Internet Explorer, Firefox, Chrome, and Safari. That also means you don’t need to install any other tool. All you need is a web browser. MPLAB Xpress Board Let’s start by quickly checking out the package, board, and offline documentation. Once you open the package, you’ll get the board, a folded sheet of paper for the schematics, and some information on the package itself with the pinout diagram, and a quick start guide explaining that the board acts as a mass storage device, and all you need is a web browser for […]
