NO.5 An automotive chip that gets more expensive the more you use it

ATMEGA328P-AU: Price remains high

ATMEGA328P-AU is currently at a high price after the increase, but has slightly decreased to between 150-200 yuan.

ATMEGA328P-AU is a low-power, high-performance 8-bit microcontroller from Microchip’s ATMEL AVR series, officially recommended for automotive use, with an official price of about 2.5 USD (approximately 16 yuan).

Naming rules

ATmega48A/PA/88A/PA/168A/PA/328/P are all low-power, CMOS 8-bit microcontrollers based on the enhanced RISC architecture of AVR®.

ATMEGAXXX XX-XX XX

XXX = 8, 16, 48, 128, 328, etc.;

XX = “ P” for low voltage, energy-saving technology, followed by the voltage range: with “ V” indicates 1.8V-5.5V, without “V” indicates 2.7-5.5V, L for low frequency;

XX = 20, 10 indicates clock frequency;

XX = specification information;

• The first letter indicates the package

P:DIP package, A:TQFP package, M:MLF package

For example, ATMEGA48PV-10AU represents: model is ATMEGA48, uses energy-saving technology, voltage range: 1.8V-5.5V, clock frequency: 10, TQFP package, industrial grade lead-free.

ATMEGA328P-AU has roughly fluctuated in price since October last year, and has significantly increased by the end of the year. Currently, compared to the price of ATMEGA328P-AU in January 2022, it has doubled again. Since February, the demand for automotive and industrial control focused on Microchip has surged, and on March 1, Microchip issued a price increase notice (by 6%-10%), with delivery times reaching over 50 weeks.

It is said that Microchip’s QFN package chips ending with ML have no inventory, and the demand for automotive electronics is expected to remain strong in the second half of the year.

NO.6 Dangerous yet charming

SAK-TC277TP-64F200N DC: Who can withstand this price

Market prices in April continue to soar, having exceeded 4000 yuan.
