Product Description
Value line, Cortex-M4 120MHz CPU, 16~64KB Flash, 16KB SRAM, ADC,COMP MCU AT32F421 Microcontroller
AT32F421 Series
AT32F421 (value line) series microcontroller incorporates ARM® Cortex®-M4 core, up to 120 MHz CPU computing speed and embedded data signal processor (DSP) supporting up to 64 KB Flash memory and 16 KB SRAM, up to 2 x USARTs, 2 x SPIs (multiplexed I²S), 2x I²Cs, a 16-bit advanced timer, 5 x 16-bit general-purpose timers and 5-channel DMA controller, and also includes two high-speed rail to rail input/output analog voltage comparators, a 12-bit 15 channels high-speed ADC with 2M SPS that meet the requirements of high-speed data acquisition, mixed signal processing, industrial control and motor applications. Almost fast I/Os are 5 V-tolerant with a variety of optional functions to support function remapping, excellent flexibility and ease of use to implement various applications.
AT32F421 series is equipped with the Security Library (sLib) developed by Artery, supporting the use of password to protect the specified program area so that IDH can program the core algorithm into this area and provides it to downstream customers for secondary development, which increases the security, reliability and convenience for secondary development.
AT32F421 devices can run well in the temperature range of -40 to 105°C , and provides a wide range of chips for selection, such as LQFP48, LQFP32, QFN32, QFN28 and mini TSSOP20 in response to diverse memory needs. Its powerful on-chip resource allocation, high integration, cost-effective performance bring up the first-class competitive edge in the chip market.

Packing & Delivery
Packing:
Machine packing inside is plastic films and outside is fumigation wooden case.
Our wooden case is very strong,it can bear long time shipping on the sea.
And machine with preservative film, it can stop the salt sea water enter into the machine and make the machine corrosion.
Delivery:
For machines are big and heavy parcel, and different country with different delivery cost,so we suggest below delivery solution:
1. Over 1CBM or 100KG, we suggest send by Sea.
2. Below 1CBM or 100KG, we suggest send by Air.
3. Below 0.5CBM or 50KG, we suggest send by Express.
The price show on our website just the machine EXW price, please contact us for confirm delivery cost before you place order.
