ST10F276Z5Q3 832KBit Flash,68KBit RAM,16位微控制器LQFP-144封装

ST10F276Z5Q3 概述

The ST10F276Z5 is a derivative of the STMicroelectronics ST10 family of 16-bit single-chip CMOS microcontrollers. It combines high CPU performance (up to 32 million instructions per second) with high peripheral functionality and enhanced I/O-capabilities. It also provides on-chip high-speed single voltage Flash memory, on-chip high-speed RAM, and clock generation via PLL. The ST10F276Z5 is processed in 0.18 μm CMOS technology. The MCU core and the logic is supplied with a 5 to 1.8 V on-chip voltage regulator. The part is supplied with a single 5 V supply and I/Os work at 5 V.The device is upward compatible with the ST10F269 device, with the following set of differences:

1. Flash control interface is now based on STMicroelectronics third generation of standalone Flash memories (M29F400 series), with an embedded Program/Erase Controller.This completely frees up the CPU during programming or erasing the Flash.
2. Only one supply pin (ex DC1 in ST10F269, renamed into V18) on the QFP144 package is used for decoupling the internally generated 1.8 V core logic supply. Do not connect this pin to 5.0 V external supply. Instead, this pin should be connected to a decoupling capacitor (ceramic type, typical value 10 nF, maximum value 100 nF).
3. The AC and DC parameters are modified due to a difference in the maximum CPU frequency.
4. A new VDD pin replaces DC2 of ST10F269.
5. EA pin assumes a new alternate functionality: it is also used to provide a dedicated power supply (see VSTBY) to maintain biased a portion of the XRAM (16Kbytes) when the main Power Supply of the device (VDD and consequently the internally generated V18) is turned off for low power mode, allowing data retention. VSTBY voltage shall be in the range 4.5-5.5 V, and a dedicated embedded low power voltage regulator is in charge to provide the 1.8 V for the RAM, the low-voltage section of the 32 kHz oscillator and the real-time clock module when not disabled. It is allowed to exceed the upper limit up to 6 V for a very short period of time during the global life of the device, and exceed the lower limit down to 4 V when RTC and 32 kHz on-chip oscillator are not used.
6. A second SSC mapped on the XBUS is added (SSC of ST10F269 becomes here SSC0, while the new one is referred as XSSC or simply SSC1). Note that some restrictions and functional differences due to the XBUS peculiarities are present between the classic SSC, and the new XSSC.
7. A second ASC mapped on the XBUS is added (ASC0 of ST10F269 remains ASC0,while the new one is referred as XASC or simply as ASC1). Note that some restrictions and functional differences due to the XBUS peculiarities are present between the classic ASC, and the new XASC.
8. A second PWM mapped on the XBUS is added (PWM of ST10F269 becomes here PWM0, while the new one is referred as XPWM or simply as PWM1). Note that some restrictions and functional differences due to the XBUS peculiarities are present between the classic PWM, and the new XPWM.
9. An I²C interface on the XBUS is added (see X-I²C or simply I²C interface).
10. CLKOUT function can output either the CPU clock (like in ST10F269) or a software programmable prescaled value of the CPU clock.
11. Embedded memory size has been significantly increased (both Flash and RAM).
12. PLL multiplication factors have been adapted to new frequency range.
13. A/D Converter is not fully compatible versus ST10F269 (timing and programming model). Formula for the conversion time is still valid, while the sampling phase programming model is different. Besides, additional 8 channels are available on P1L pins as alternate function: the accuracy reachable with these extra channels is reduced with respect to the standard Port5 channels.
14. External Memory bus potential limitations on maximum speed and maximum capacitance load could be introduced (under evaluation): ST10F276Z5 will probably not be able to address an external memory at 64 MHz with 0 wait states (under evaluation).
15. XPERCON register bit mapping modified according to new peripherals implementation (not fully compatible with ST10F269).
16. Bond-out chip for emulation (ST10R201) cannot achieve more than 50 MHz at room temperature (so no real-time emulation possible at maximum speed).
17. Input section characteristics are different. The threshold programmability is extended to all port pins (additional XPICON register); it is possible to select standard TTL (with up to 500 mV of hysteresis) and standard CMOS (with up to 800 mV of hysteresis).
18. Output transition is not programmable.
19. CAN module is enhanced: the ST10F276Z5 implements two C-CAN modules, so the programming model is slightly different. Besides, the possibility to map in parallel the two CAN modules is added (on P4.5/P4.6).
20. On-chip main oscillator input frequency range has been reshaped, reducing it from 1-25 MHz down to 4-12 MHz. This is a high performance oscillator amplifier, providing a very high negative resistance and wide oscillation amplitude: when this on-chip amplifier is used as reference for real-time clock module, the power-down consumptionis dominated by the consumption of the oscillator amplifier itself. A metal option is added to offer a low power oscillator amplifier working in the range of 4-8 MHz: this willallow a power consumption reduction when real-time clock is running in Power-down mode using as reference the on-chip main oscillator clock.
21. A second on-chip oscillator amplifier circuit (32 kHz) is implemented for low power modes: it can be used to provide the reference to the real-time clock counter (either in Power-down or Standby mode). Pin XTAL3 and XTAL4 replace a couple of VDD/VSS pins of ST10F269.
22. Possibility to re-program internal XBUS chip select window characteristics (XRAM2 and XFLASH address window) is added.
