Release date2020 May 11
Product details
CPUNXP IMXRT1062DVJ6A ARM Cortex-M7 at 600 MHz with FPU (32 bit float and 64 bit double precision), DSP instructions.
RAM1.024 KB RAM (512K tightly coupled)
ROM (Flash)7.936 KB Flash
SPIYes 2
USB HostYes 2 usb ports (1 as USB host, 5 pin header with power management)
Ethernet (LAN, RJ45)Yes Ethernet 10/100 Mbit (6 pin on board header). Teensy 4.1 contains an Ethernet controller and Ethernet PHY chip.
RTC Memory16 bytes of memory are located within the RTC. If a coin cell is connected to VBAT, contents of this memory is preserved while power is off. This memory is accessed as 32 bit registers LPGPR0-LPGPR3.
External SPIRAM16 MB up to PSRAM (QSPI Memory Expansion, ready to solder 1 or 2 chips such as IPS6404LSQ or ESP PSRAM64H on board)
External Flash8 MB up to (QSPI Memory Expansion, board ready to solder additional 8MB Flash chip such as 25Q128JVSQ)
CANYes 3
