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. 3 May 2022 ---------- Zero STM32F0xx in stock.
