What is the range of LPC2148 on-chip SRAM and Flash memory?
The LPC2141/42/44/46/48 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combine the microcontroller with embedded high-speed flash memory ranging from 32 kB to 512 kB.
How many DAC lines are available in LPC2148?
from digital values. LPC2148 has 10-bit DAC with resistor string architecture. It also works in Power down mode. LPC2148 has Analog output pin (AOUT) on chip, where we can get digital value in the form of Analog output voltage.
How many registers is LPC2148?
Pin Function Select Registers These registers are used to select or configure specific pin functionality. There are 3 Pin Function Select Registers in LPC2148: 1.
Is LPC2148 Having inbuilt DAC?
from digital values. LPC2148 has 10-bit DAC with resistor string architecture. LPC2148 has Analog output pin (AOUT) on chip, where we can get digital value in the form of Analog output voltage. The Analog voltage on AOUT pin is calculated as ((VALUE/1024) * VREF).
How many timers are available on LPC2148?
LPC2148 has two 32-bit timers/counters:Timer0/Counter0 & Timer1/Counter1.
What is size of ADC in LPC2148?
10-bit
LPC2148 ADC Block LPC2148 has an inbuilt 10-bit Successive Approximation ADC which is multiplexed among 6/8 input pins of ADC0/ADC1. The ADC reference voltage is measured across GND to VREF, meaning it can do the conversion within this range.
What is resolution of LPC2148 on chip DAC?
LPC2148 has the 10 bit resolution ADC. With this if the actual input voltage is 0V then the MCU’s ADC will read it as 0 and if it is 3.3V the MCU will read 1024 and if it somewhere in between like 1.65v then the MCU will read 512.
How much memory is available in LPC2148?
