March 2022

There are No STM32F, G or H micros at arrow.com, in fact they haven’t had any for at least six months. Even 6 months ago, they were down to a few really low end STM32F0xx units.

All Arrow has in March are some STM32L chips at $8 AUD each, min qty 250.

I took the opportunity to buy 400x MSP430FR2632 in March. It’s a tiny MCU, 24 pins in only 2.3 x 2.3 mm BGA24 (5 rows of 5). Will I be able to deploy them ?

11 April 2022

Arrow.com actually has 400 parts MCU 32-bit ARM Cortex M0+ RISC 32KB Flash 2.5V/3.3V 28-Pin UFQFPN Tray at A$6.00 in stock. Expensive, but this is the new normal I think.

MSP430FR2632 at $1.3956 AUD each.

MSP430FR2632 are now $1.17 AUD ea.
