7 MSC - Memory System Controller
7.1 Introduction
7.2 Features
2010-09-06 - d0001_Rev1.00
The Memory System Controller (MSC) is the program memory unit of the EFM32G microcontroller. The
flash memory is readable and writable from both the Cortex-M3 and DMA. The flash memory is divided
into two blocks; the main block and the information block. Program code is normally written to the main
block. Additionally, the information block is available for special user data and flash lock bits. There is
also a read-only page in the information block containing system and device calibration data. Read and
write operations are supported in the energy modes EM0 and EM1.
• AHB read interface
0 1 2 3
• Scalable access performance to optimize the Cortex-M3 code interface
• Zero wait-state access up to 16 MHz and one wait-state for 16 MHz and above
• Advanced energy optimization functionality

What?
The user can perform Flash memory read,
read configuration and write operations
through the Memory System Controller
(MSC) .
Why?
The MSC allows the application code, user
data and flash lock bits to be stored in non-
volatile Flash memory. Certain memory
system functions, such as program memory
wait-states and bus faults are also configured
from the MSC peripheral register interface,
giving the developer the ability to dynamically
customize the memory system performance,
security level, energy consumption and error
handling capabilities to the requirements at
hand.
How?
The MSC integrates a low-energy Flash
IP with a charge pump, enabling minimum
energy consumption while eliminating the
need for external programming voltage to
erase the memory. An easy to use write and
erase interface is supported by an internal,
fixed-frequency oscillator and autonomous
flash timing and control reduces software
complexity while not using other timer
resources.
Application code may dynamically scale
between high energy optimization and
high code execution performance through
advanced read modes.
