Microchip Releases Tiny SAM R34/R35 LoRa SiPs and Development Kit

Microchip SAM R34

Microchip has been offering RN2483 & RN2903 LoRa modules for respectively 868 MHz and 915 MHz frequencies for several years, but the company has now announced SAM R34 and SAM R35 LoRa systems-in-package (SiP) that offer similar functionality in a much smaller form factor. Both SiPs integrate a Microchip SAM L21 Arm Cortex-M0+ based MCU,a sub-GHz RF LoRa transceiver operating from 862 to 1020 MHz, and a software stack. That means you don’t need different SiP depending on the region, and the only difference between SAM R34 and SAM R35 is the latter does without a USB interface for lower cost. Microchip SAM R34/R35 key features and specifications: MCU – Arm Cortex M0+ MCU @ 48 MHz System Memory – Up to 40 KB RAM including 8KB LP-RAM Storage – Up to 256 KB Flash for application code and stack Wireless Connectivity 862 MHz to 1020 MHz coverage Up to 20 dBm (100 mW) max power Up to +13 dBm (20 …

Microchip Launches $39 Industrial Grade System-on-Module with SAMA5D2 System-in-Package

Last fall, Microchip introduced four SAMA5D2 systems-in-package (SiP) combining the Cortex A5 processor with 16 to 128 MB DDR2 in a single package, and at the time, the company also offered ATSAMA5D27-SOM1-EK1, a fast prototyping and evaluation platform for the SiP that was designed with a baseboard and a soldered down ATSAMA5D27-SOM1 system-on-module. The kit was available for $245, and pricing for the SiP started at around $9 per unit for 5K order.

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 289 BGA Package Designed for small Linux OS applications ATSAMA5D27C-D1G …

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 > Vtrip), the content of the EEPROM is copied back into …
