The addition of DDR2 memory, a first for MCUs throughout
the industry, enables 2x faster throughput and large
graphics buffers and/or storage for increasingly complex
communications protocol stacks and algorithms. The result
is smooth, striking interfaces and fewer product variants in
a crowded communications control market.
The PIC32MZDAfamily is supported byMicrochip’sMPLAB
Harmony Integrated Software Framework, MPLAB X
Integrated Development Environment (IDE), MPLAB XC32
Compiler for PIC32, MPLAB ICD 3 In-Circuit Debugger and
MPLAB REAL ICE™ In-Circuit Emulation System.
Several additional tools are available including:
PIC32MZ Embedded Graphics with Stacked DRAM (DA)
Starter Kit (DM320010) at $130
PIC32MZ Embedded Graphics with Stacked DRAM (DA)
Starter Kit (Crypto) (DM320010-C) at $130
PIC32MZ Embedded Graphics with External DRAM (DA)
Starter Kit (DM320008) at $140
PIC32MZ Embedded Graphics with External DRAM (DA)
Starter Kit (Crypto) (DM320008-C) at $140
Devices in the PIC32MZ DA family are offered in a variety
of package options including a 169-ball BGA, a 176-pin
LQFP and a 288-ball BGA for external DDR2 applications.
Devices in the family are available today in volume
production.

Analog Devices’ Small Isolated Gate Drivers
Deliver Solutions for Next Generation Power
Switch Technology
Anlog Devices, Inc. (ADI) announced small form factor
isolated gate drivers designed for the higher switching
speeds and system size constraints required by power
switch technologies such as SiC (Silicon Carbide) and
GaN (Gallium Nitride), while still providing reliable
control over switching characteristics for IGBT (insulated
gate bipolar transistor) and MOSFET (metal oxide
semiconductor field effect transistor) configurations.
The ADuM4120 and ADuM4121 series leverages
ADI’s proven iCoupler® isolation technology combined
with high speed CMOS and monolithic transformer
technology to enable ultra-low propagation delay
without sacrificing common mode transient immunity
(CMTI) performance.
While legacy alternatives such as optocouplers or
pulse transformers struggle to deliver shorter delay and
maintain CMTI performance, the robust ADuM4120 and
ADuM4121 are purposely designed to enable the higher
switching speeds of the new inverter architectures.
In systems requiring multiple power switches, these
small SOIC packaged isolated gate drivers minimize
PCB layout space subsequently reducing cooling
requirements. Additionally, their small size allows the
gate drivers to be located close to the power switches
to reduce the parasitic inductance between the driver
and the switch. Operating over a high temperature
range and high working voltages, the ADuM4120 and
ADuM4121 are ideal for improving the energy efficiency
and timing performance stability of solar inverters, motor
controllers, and industrial inverter applications.
All four devices in the new series are 2 A output, single-
channel gate drivers that provide 5 kV rms isolation
with low propagation delay and CMTI performance of
>150 kV/μs. Operating with an input supply ranging
from 2.5 V to 6.5 V, these isolated gate drivers provide
compatibility with lower voltage systems with the benefit
of true galvanic isolation between the input and the
output. The ADuM4120 and ADuM4120-1 provide
thermal shutdown for over temperature protection.
The ADuM4120 with input glitch filter reduces system
noise on the input pin that could trigger a false output,
while the ADuM4120-1 without glitch filter supports low
33ns typical propagation delay. The ADuM4121 and
ADuM4121-1 are available with an internal Miller clamp
for added protection. The ADuM4121 device is also
available with the thermal shutdown. By offering gate
