1 Overview
1.1
Features
AT-START-F435
has the following characteristics:

AT-START-F435
has an on-board AT32F435ZMT7 microcontroller that embeds ARM Cortex
®
-
M4F 32-bit core with FPU, 4032 KB Flash memory and 384 KB SRAM, in LQFP144 packages.

On-board AT-Link interface:
−
On-board AT-Link-EZ can be used for programming and debugging (AT-Link-EZ is a
simplified version of AT-Link, without offline mode support)
−
If AT-Link-EZ were disassembled from the board by bending it along the joint, this interface
can be connected to an independent AT-Link for programming and debugging.

On-board 20-pin ARM standard JTAG interface (can be connected to JTAG or SWD connector
for programming and debugging)

16 MB SPI (EN25QH128A) is used as extended Flash memory

Various power supply methods:
−
USB bus of AT-Link-EZ
−
OTG1 or OTG2 bus (V
BUS1
or V
BUS2
) of AT-START-F435
−
External 5 V power supply (E5V)
−
External 3.3 V power supply

4 x LED indicators:
−
LED1 (red) indicates 3.3 V power-on
−
3 x USER LEDs, LED2 (red),LED3 (yellow) and LED4 (green), indicate operation status

User button and Reset button

8 MHz HEXT crystal

32.768 kHz LEXT crystal

On-board USB type-A and micro-B connectors in order to demonstrate OTG1 function

OTG2 has micro-B connector (If the user wants to use OTG2 master mode, an adapter cable
is required)

Rich extension interfaces are available for quick prototyping
−
Arduino
TM
Uno R3 extension interface
−
LQFP144 I/O extension interface
