2.1.19 Analog Comparator (ACMP)

The Analog Comparator is used to compare the voltage of two analog inputs, with a digital output indi-

cating which input voltage is higher. Inputs can either be one of the selectable internal references or from

external pins. Response time and thereby also the current consumption can be configured by altering

the current supply to the comparator.

2.1.20 Voltage Comparator (VCMP)

The Voltage Supply Comparator is used to monitor the supply voltage from software. An interrupt can

be generated when the supply falls below or rises above a programmable threshold. Response time and

thereby also the current consumption can be configured by altering the current supply to the comparator.

2.1.21 Analog to Digital Converter (ADC)

The ADC is a Successive Approximation Register (SAR) architecture, with a resolution of up to 12 bits

at up to one million samples per second. The integrated input mux can select inputs from 8 external

pins and 6 internal signals.

2.1.22 Digital to Analog Converter (DAC)

The Digital to Analog Converter (DAC) can convert a digital value to an analog output voltage. The DAC

is fully differential rail-to-rail, with 12-bit resolution. It has two single ended output buffers which can be

combined into one differential output. The DAC may be used for a number of different applications such

as sensor interfaces or sound output.

2.1.23 Operational Amplifier (OPAMP)

The EFM32GG230 features 3 Operational Amplifiers. The Operational Amplifier is a versatile general

purpose amplifier with rail-to-rail differential input and rail-to-rail single ended output. The input can be set

to pin, DAC or OPAMP, whereas the output can be pin, OPAMP or ADC. The current is programmable

and the OPAMP has various internal configurations such as unity gain, programmable gain using internal

resistors etc.

2.1.24 Low Energy Sensor Interface (LESENSE)

The Low Energy Sensor Interface (LESENSE^TM), is a highly configurable sensor interface with support

for up to 16 individually configurable sensors. By controlling the analog comparators and DAC, LESENSE

is capable of supporting a wide range of sensors and measurement schemes, and can for instance mea-

sure LC sensors, resistive sensors and capacitive sensors. LESENSE also includes a programmable

FSM which enables simple processing of measurement results without CPU intervention. LESENSE is

available in energy mode EM2, in addition to EM0 and EM1, making it ideal for sensor monitoring in

applications with a strict energy budget.

2.1.25 Backup Power Domain

The backup power domain is a separate power domain containing a Backup Real Time Counter, BURTC,

and a set of retention registers, available in all energy modes. This power domain can be configured to

automatically change power source to a backup battery when the main power drains out. The backup

power domain enables the EFM32GG230 to keep track of time and retain data, even if the main power

source should drain out.

2.1.26 Advanced Encryption Standard Accelerator (AES)

The AES accelerator performs AES encryption and decryption with 128-bit or 256-bit keys. Encrypting or

decrypting one 128-bit data block takes 52 HFCORECLK cycles with 128-bit keys and 75 HFCORECLK

cycles with 256-bit keys. The AES module is an AHB slave which enables efficient access to the data
