49 / 88 page ![]() MSP430x20x1, MSP430x20x2, MSP430x20x3 MIXED SIGNAL MICROCONTROLLER SLAS491D -- AUGUST 2005 -- REVISED SEPTEMBER 2007 49 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 electrical characteristics over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (continued) Flash Memory PARAMETER TEST CONDITIONS VCC MIN TYP MAX UNIT VCC(PGM/ ERASE) Program and Erase supply voltage 2.2 3.6 V fFTG Flash Timing Generator frequency 257 476 kHz IPGM Supply current from VCC during program 2.2 V/3.6 V 1 5 mA IERASE Supply current from VCC during erase 2.2 V/3.6 V 1 7 mA tCPT Cumulative program time (see Note 1) 2.2 V/3.6 V 10 ms tCMErase Cumulative mass erase time 2.2 V/3.6 V 20 ms Program/Erase endurance 104 105 cycles tRetention Data retention duration TJ =25°C 100 years tWord Word or byte program time 30 tBlock, 0 Block program time for 1st byte or word 25 tBlock, 1-63 Block program time for each additional byte or word see Note 2 18 t tBlock, End Block program end-sequence wait time seeNote2 6 tFTG tMass Erase Mass erase time 10593 tSeg Erase Segment erase time 4819 NOTES: 1. The cumulative program time must not be exceeded when writing to a 64-byte flash block. This parameter applies to all programming methods: individual word/byte write and block write modes. 2. These values are hardwired into the Flash Controller’s state machine (tFTG =1/fFTG). RAM PARAMETER TEST CONDITIONS MIN TYP MAX UNIT V(RAMh) RAM retention supply voltage (see Note 1) CPU halted 1.6 V NOTE 1: This parameter defines the minimum supply voltage VCC when the data in RAM remains unchanged. No program execution should happen during this supply voltage condition. |
