— TX warm-up is 92 s
— Turnaround times
– The IEEE 802.15.4 Standard requires a TX-to-RX or a RX-to-TX turnaround time to be less
than or equal to 12 symbols times (192 s).
– Best practice for maximum station-to-station performance is to minimize TX-to-RX
turnaround time and to maximize (within spec) RX-to-TX turnaround time.
– Auto sequences should use recommended turnaround times of:
a) 11 symbols times (176 s) RX-to-TX
b) 96 s TX-to-RX.
Dedicated DMA for transfer of TX/RX data from/to RAM (minimum bus clock of 2 MHz for
802.15.4 modem operation)
Maskable, event-driven interrupt generation
Address header filtering for received packets. A promiscuous mode allows bypass of the filtering
for monitoring network traffic
Packet manager
— Handles preamble data
— Handles frame check sequence (FCS) a.k.a CRC
— Embedded header filter for received packets
Control/status registers mapped into CPU memory map
32-Bit random number generator — Runs at the bus clock rate, a 32-bit Linear Feedback Shift
Register (LFSR) can be set with a seed value and uses a 32-bit primitive polynomial. A 32-bit
random number is fetched with every read of the proper control register

Advanced Security Module (ASM)
The IEEE 802.15.4 Standard and the ZigBee Standard both provide for optional use of data encryption.The
ASM engine is a hardware block that accelerates encryption/decryption using the Advanced Encryption
Standard (AES). The engine can perform “Counter” (CTR) and Cipher Block Chaining (CBC) encryption.
The combination of these two modes of encryption are known as CCM mode encryption. CCM is short for
Counter with CBC-MAC. CCM is a generic authenticate and encrypt block cipher mode. CCM is only
defined for use with 128 bit block ciphers, such as AES. The definition of CCM mode encryption is
documented in the NIST publication SP800-38C.
The ASM has the following features:
32-Bit wide bus interface
CTR encryption in 13 clock cycles
CBC encryption in 13 clock cycles
Encrypts 128 bits as a unit
The 128-bit registers are aligned on quad word boundaries (16 byte)
Self-test mode
Maskable “action complete” interrupt
