Report
ECE 56800 - Embedded Systems Name: Ashish Chaudhary 1. What is the supply voltage range of this MCU? Ans. The supply voltage range during program execution is 1.8V to 3.6V. (Page 32, table - Recommended operating conditions) 2. What is the total program memory size and the total RAM size of the MCU? Ans. Total program memory (Flash or ROM Memory) size is 92KB+256B and RAM size is 8KB. (Page 1) 3. How many external crystal oscillators can you add? Ans. We can add two crystal oscillators: XT1((XIN, XOUT) & XT2(XT2IN, XT2OUT) (Page 7 & Page 9: MSP430x461x Terminal Functions and page 6: MSP430x461x functional block diagram) 4. Compare the two block diagrams on pages 5 and 6. What is the most important difference? Which one applies to this MCU? Ans. The block diagram on page 5 is for MSP430x461x and on page 6 is for MSP430x461x1. Page 6 applies to this MCU. The most important difference is ADC, MSP430x461x has 12-bit 12-channel ADC while MSP430x461x1 does not have any ADC. 5. See the “recommended operating conditions” table on page 32. What is the operating free-air temperature range? Ans. The operating free-air temperature range is -40 o C to 85 o C. (Page 32, table - Recommended operating conditions) 6. What is the maximum operating frequency when the supply voltage is 2.0 V? Ans. The maximum operating frequency when the supply voltage is 2.0 V is 4.6MHz. (Page 32, Figure 1 - Plot for Supply voltage vs Frequency) 7. How many timers does the MCU have? How many Capture/Compare Unit does each timer have? Ans. MCU has 2 timers, Timer A and Timer B. Timer A has 3 capture compare regs and Timer B has 7 capture compare regs. (Page1) 8. What is the base address (lowest address) of the RAM on the memory map? Ans. The Base address of RAM on the memory map is 0x030FFh. (Page 18, table - Memory Organization) 9. In this memory-mapped I/O MCU, the control register for Timer_B, named “TBCTL” has a unique address on the memory map. What is it? Ans: The unique address for Timer B on the memory map is 0x0180. (Page 25, table: Peripherals with word access) 10. What is the package type of this MCU? What is the nominal size of this MCU, from pin to pin?
Ans: The package type of this MCU is LQFP. (Page - Pack Materials - Page 1). The Nominal size of this MCU, from pin to pin, is 0.5mm. (Page- Mechanical data - Page 1)
