Large memory, low pin-count MCUs
30 April 2008
DSP, Micros & Memory
A range of new 28- and 44-pin 16-bit devices is available from Microchip, featuring increased memory, performance and enhanced peripherals. The new devices include 10 PIC24H 16-bit microcontrollers offering up to 128 KB of programmable Flash memory, up to 16 KB of SRAM (including 2 KB of dual-port RAM for DMA), two on-chip comparators, a user-selectable 10-bit or 12-bit ADC with up to four Sample and Hold circuits in 10-bit mode, and a realtime clock calendar module. Standard serial communication peripherals include two SPIs, two UARTs and one I C module. The new families are offered in packages as small as 6 x 6 mm, and operate at up to 40 MIPS. The devices feature Peripheral Pin Select, which allows digital peripheral pins to be remapped in order to achieve layout efficiency or access to pin-multiplexed peripherals. They also offer a Parallel Master Port for rapid parallel communication with off-chip resources, such as displays, communication peripherals or memory.

Low-power memory born for edge AI
iCorp Technologies
DSP, Micros & Memory
As intelligence moves from the cloud to the device, memory become one of the most important design decisions in modern electronics. Edge-AI products – from smart speakers and surveillance cameras to ADAS modules and wearables – need to move data fast, but they also need to sip power. Winbond’s low-density LPDDR4/LPDDR4X SDRAM range is built to strike that balance.
