EM250
The EM250 integrates hardware support for a Packet Trace module, which allows robust packet-based debug.
This element is a critical component of Ember Desktop, the Ember software IDE, providing advanced network
debug capability when coupled with the Ember Debug Adapter (ISA).
The EM250 integrates a 16-bit XAP2b microprocessor developed by Cambridge Consultants Ltd. This power-
efficient, industry-proven core provides the appropriate level of processing power to meet the needs of
ZigBee applications. In addition, 128kB of Flash and 5kB of SRAM comprise the program and data memory
elements, respectively. The EM250 employs a configurable memory protection scheme usually found on larger
microcontrollers. In addition, the SIF module provides a non-intrusive programming and debug interface
allowing for real-time application debugging.
The EM250 contains 17 GPIO pins shared with other peripheral (or alternate) functions. Flexible routing within
the EM250 lets external devices utilize the alternate functions on a variety of different GPIOs. The integrated
Serial Controller SC1 can be configured for SPI (master-only), I 2 C (master-only), or UART functionality, and the
Serial Controller SC2 can be configured for SPI (master or slave) or I 2 C (master-only) operation.
The EM250 has an ADC integrated which can sample analog signals from four GPIO pins single-ended or
differentially. In addition, the unregulated voltage supply VDD_PADS, regulated supply VDD_PADSA, voltage
reference VREF, and GND can be sampled. The integrated voltage reference VREF for the ADC can be made
available to external circuitry.
The integrated voltage regulator generates a regulated 1.8V reference voltage from an unregulated supply
voltage. This voltage is decoupled and routed externally to supply the 1.8V to the core logic. In addition, an
integrated POR module allows for the proper cold start of the EM250.
The EM250 contains one high-frequency (24MHz) crystal oscillator and, for low-power operation, a second low-
frequency oscillator (either an internal 10kHz RC oscillator or an external 32.768kHz crystal oscillator).
The EM250 contains two power domains. The always-powered High Voltage Supply is used for powering the
GPIO pads and critical chip functions. The rest of the chip is powered by a regulated Low Voltage Supply which
can be disabled during deep sleep to reduce the power consumption.
