Low-Power SoC (System-on-Chip) with MCU, Memory, 2.4 GHz RF Transceiver, and USB Controller

The CC2510Fx/CC2511Fx is a true low-cost 2.4 GHz system-on-chip (SoC) designed for low power wireless applications. The CC2510Fx/CC2511Fx combines the excellent performance of the state-of-the-art RF transceiver CC2500 with an industry-standard enhanced 8051 MCU, up to 32 KB of in-system programmable flash memory and 4 KB of RAM, and many other powerful features. The small 6x6 mm package makes it very suited for applications with size limitations.

The CC2510Fx/CC2511Fx is highly suited for systems where very low power consumption is required. This is ensured by several advanced low-power operating modes. The CC2511Fx adds a full-speed USB controller to the feature set of the CC2510Fx. Interfacing to a PC using the USB interface is quick and easy, and the high data rate (12 Mbps) of the USB interface avoids the bottlenecks of RS-232 or low-speed USB interfaces.

Key Features:

High-Performance and Low-Power 8051-Compatible Microcontroller

● Configurable FIFO size for IN and OUT direction of endpoint

Full-Speed USB Controller (CC2511Fx )
● 8, 16, or 32 KB of non-volatile flash memory, in-system programmable through
　a simple two-wire interface or by the 8051 core
● Minimum flash memory endurance:1000 write/erase cycles
● Programmable read and write lock of portions of flash memory for software security
● 1, 2, or 4 KB of internal SRAM

I²S Interface
● Industry standard I²S interface for transfer of digital audio data
● Full duplex
● Mono and stereo support
● Configurable sample rate and sample size
● Support for μ-law compression and expansion
● Typically used to connect to external DAC or ADC

Hardware AES Encryption/Decryption
● 128-bit AES supported in hardware coprocessor

Peripheral Features
● Powerful DMA Controller
● Power On Reset/Brown-Out Detection
● ADC with eight individual input channels, single-ended or differential
　(CC2511Fx has six channels) and configurable resolution
● Programmable watchdog timer
● Five timers: one general 16-bit timer with DSM mode, two general 8-bit timers,
　one MAC timer, and one sleep timer
● Two programmable USARTs for master/slave SPI or UART operation
● 21 configurable general-purpose digital I/O-pins (CC2511Fx has 19)
● Random number generator

Low Power
● Four flexible power modes for reduced power consumption
● System can wake up on external interrupt or when the Sleep Timer expires
● 0.5 μA current consumption in PM2, where external interrupts or the
　Sleep Timer can wake up the system
● 0.3 μA current consumption in PM3, where external interrupts can wake up the system
● Low-power fully static CMOS design
● System clock source is either a high speed crystal oscillator
　 (24 - 27 MHz for CC2510Fx and 48 MHz for CC2511Fx) or a high speed RC oscillator
　 (12 - 13.5 MHz for CC2510Fx and 12 MHz for CC2511Fx). The high speed crystal
　 oscillator must be used when the radio is active.
● Clock source for ultra-low power operation can be either a low-power RC oscillator
　or an optional 32.768 kHz crystal oscillator
● Very fast transition to active mode from power modes enables ultra low
　average power consumption in low duty-cycle systems

2.4 GHz Radio with Baseband Modem
● Based on the industry leading CC2500 radio core
● Few external components: On-chip frequency synthesizer, no external filters or
　RF switch needed
● Flexible support for packet oriented systems: On-chip support for sync word
　detection, address check, flexible packet length, and automatic CRC handling
● Supports use of DMA for both RX and TX resulting in minimal CPU intervention
　even on high data rates
● Programmable channel filter bandwidth
● 2-FSK, GFSK and MSK supported
● Optional automatic whitening and dewhitening of data
● Programmable Carrier Sense (CS) indicator
● Programmable Preamble Quality Indicator for detecting preambles and
　improved protection against sync word detection in random noise
● Support for automatic Clear Channel Assessment (CCA) before transmitting
　 (for listen-before-talk systems)
● Support for per-package Link Quality Indication (LQI)
● Suited for systems targeting compliance with EN 300 328, EN 300 440,
　FCC CFR47 Part 15 and ARIB STD-T-66
