Hello,

I'm working on a S6BT112A design without a MCU and can therefore not simply delay the rise of NSLP on Power-On.

Would it be a valid design to connect NSLP permanently to +5V?

Would this put the S6BT112A into Normal Mode after Power On?

+5V would be available sooner to the circuit than V_Bat, could this be an issue if the NSLP & SELMS Pins are driven high before the Bat Pin is powered?

Here is a quick illustration of my intended circuit.

Best Regards

Hello,

When a software watchdog reset (SWDGR) occurs, if DSRAMR is set correctly, is the data in SRAM2 retained?

At this time, the data in SRAM0/1 can not be retained, is this right?

I'm using an MB9BF368R with IAR Workbench and PDL 2.1.

When I'm trying to write an 16-bit value to workflash, only 8-bit were written.

Here is my code example:

__disable_interrupt();

  uint32_t adr = 0x200C008D;

  WFlash_ChipErase();

  uint16_t test = 0x12AB;

  WFlash_WriteData16Bit((uint16_t*)adr, (uint16_t*)&test, 1);

  __enable_interrupt();

Does anyone have a code example of how to use the PDL 2.1 workflash functions?

15.3 Errata Summary mention Silicon reversion has Rev.B & Rev.C.

Which silicon reversion is Cypress current ship out?

How to identify?

Hi

I need to program the micro MB9BF418TPMC with batch files, but I can't find anything that can help me, I didn't find any shell ..
Can you help me?
Thank you

During serial programming of MB9BF568R the FLASH MCU programmer erase the working flash sector starting from 0x200C0000.

I've searched out for some FLASH MCU programmer setting, but nothing.

Is there a way to perform serial programming without erasing data flash memory?

Thanks

Mauro

I need MB9BF124 or CY9BF124 Data sheet.

Can anyone give us up?
