AdBun-M46B

AdBun-M46B development board for Toshiba TMPM46BF10FG MCU.

Overview

The TMPM46BF10FG is ARM® Cortex®-M4F based microcontroller for use in secure systems control, enhanced security features, ideally suited to applications in Internet of Things (IoT) devices, energy management systems, sensor technology, and industrial equipment.

Based on an ARM Cortex-M4F core, with a maximum operating frequency of 120 MHz, the TMPM46BF10FG incorporates 1024 Kbyte of flash memory and 514 Kbyte SRAM required for secure communications control, four types of security circuits for network communications. The MCU also integrates an SLC NAND flash memory controller and 4- and 8-bit error correction circuitry (BCH ECC) that supports memory expansion with 1Gbit to 4Gbit SLC NAND flash memory chips.

To provide additional levels of safety, the IC includes a 16 channel interrupt input and a clock-independent watchdog timer, which operates separately from the system clock, improving the safety of system functions. In the case of a system clock malfunction, the watchdog timer is still capable of detecting errors.

Pin Layout

CN4 Pin Header

The green-framed pins of CN4 are working with 3.3V I/O without level-shifting and connected to the terminal of TMPM46B.

CN11 Pin Header

The green-framed pins of CN11 are connected to the terminal of TMPM46B and working with 3.3V I/O without level-shifting, therefore PJ2 to PJ7 can work as Analog IN with maximum voltage of 3.3V.

Arduino Pin Header

When you use Arduino pin, you need to short that connected Arduino pin on CN4, CN9, and CN11. E.g. short: 23-24, 25-26, 27-28 etc: CN11 Arduino pin header of AdBun-M46B Supports 5V I/O only. PJ2 to PJ7 with level-shifting cannot work as Analog IN anymore.

Arduino Pin Header Usage Setting

When using the Arduino's pin header, it is necessary to short-circuit the red line as shown below.

On Board Peripheral Usage Setting

When using LED, Push SW, volume, USB and Dip SW on the AdBun-M46B board, it is necessary to short-circuit the red line as shown below. The purple line is shorted at shipment. If your AdBun-M46B is not shorted purple line, you need to short-circuit purple line.

Interface Firmware

Please update the interface firmware in the following way when upgrading, or if it has been deleted for some reasons.

  1. Download Flash programmer that programming tool to program I/F firmware.
    When you use the flash programmer, you need to agree "SOFTWARE LICENSE AGREEMENT"
    Download Flash Programmer
    Download Adbun-M46B Firmware

If you update I/F firmware, before you update the firmware, you need to erase old firmware once.

How to erase I/F firmware

  1. Short CN14
